âī¸ Biblical Faith & the Cross
The contemporary understanding of religious faith is suffering from a profound psychological reduction. In the modern lexicon, faith is routinely defined as a subjective internal state — an emotional feeling of certainty, a cognitive opinion, or a blind leap across an intellectual chasm. People treat faith as a psychological fuel tank: either you have enough internal confidence to qualify, or you do not, and the moment intellectual doubt or emotional turbulence arises, the conclusion is that faith has failed. This internalised, sentimentalised view of faith is completely foreign to the world of the biblical text. When the scriptures evaluate relationship with God, they are not measuring emotional intensity or cognitive perfection. What biblical faith actually means changes everything about what God has been asking of humanity across history.
The Anatomy: Beyond Intellectual Assent
To recover the original architecture of faith, one must look at the linguistic landscape of the ancient times. The New Testament writers wrote in Koine Greek, using the noun pistis (ĪίĪĪΚĪ) and its verbal form pisteuo (ĪΚĪĪÎĩĪĪ). In the socio-political world of the first century, pistis was not a private religious feeling. It was a covenantal, relational, and political term. It denoted covenant loyalty, sworn allegiance, absolute reliability, and a public pledge of fidelity. It was the word used to describe the unyielding bond between a soldier and their commanding officer, a citizen and their sovereign, or two parties entering a binding legal covenant. The Hebrew equivalent found in the Old Testament manuscripts, emunah (×Öą××Öŧ× Ö¸×), mirrors this concrete reality. Derived from the root aman (×Ö˛×Öˇ×), it implies firmness, stability, and staying power. It is the picture of a pillar that remains structural under immense pressure.
When this framework is applied to the biblical narrative, modern assumptions collapse. The writer of James offers a devastating critique of faith reduced to mere intellectual assent: "You believe that there is one God. Good! Even the demons believe that — and shudder" (James 2:19). The demons possess flawless, orthodox theology. They harbour no intellectual doubts regarding the existence of God, nor do they question the identity of Jesus (cf. Mark 1:24). Their intellect is fully convinced of the facts, yet they are completely devoid of pistis. Why? Because cognitive belief was never the ultimate metric Jesus was asking for. The demons know exactly who God is, but they are in open rebellion against His rule. Intellectual assent without covenant loyalty changes nothing. Pistis is not the acknowledgment of a fact; it is the execution of an allegiance.
The Geography of Doubt and the Reality of Treason
If pistis is redefined as allegiance rather than emotional or cognitive certainty, the definition of its opposite must change simultaneously. The true opposite of faith is not intellectual doubt; it is apostasy, defection, and treason. A believer can experience profound intellectual uncertainty, ask agonizing questions, and still possess robust pistis. Consider Thomas in John 20. When confronted with the report of the resurrection, he demanded empirical evidence. Yet, crucially, Thomas did not defect to the Roman authorities or abandon the community of Believers. His ultimate allegiance remained anchored, even whilst his mind wrestled with the mechanics of a miracle. When he finally encountered the risen Jesus, his response was not a psychological shift in feeling, but a declaration of total ownership and vassalage: "My Lord and my God!" Faith is about where your feet are planted when the cost is high, not how emotionally serene you feel while standing there. You can have questions and still possess pistis; you can be terrified and still maintain allegiance. Jesus does not demand a flawless psychological state; He demands a permanent direction.
If faith is defined as loyalty and remaining standing when it costs something, does this not turn salvation into a human work?
If salvation depends on the endurance of human loyalty, it risks violating the foundational truth that salvation is an unearned gift of grace, entirely separate from human performance (Ephesians 2:8-9, Romans 3:28). This perspective misinterprets the function of loyalty within a covenant. Allegiance is not a currency that purchases a reward; it is the relational posture of total surrender to a rightful Sovereign. In the ancient world, when a rebel city surrendered to a merciful king, their pledge of allegiance did not earn their pardon. The pardon was entirely an act of royal clemency — grace. The allegiance was simply the mandatory posture required to receive that clemency. Furthermore, true biblical loyalty is never self-sourced; it is a human echo of the prior, objective faithfulness of God (pistis Theou). Believers extend allegiance because God has proven Himself fundamentally loyal.
If Pistis requires unwavering loyalty, how do we account for the severe moral failures of the biblical heroes?
Abraham lied about his wife out of self-preservation (Genesis 12), and David committed adultery and orchestrated a murder (2 Samuel 11). If faith is absolute loyalty, did their failures mean their pistis failed completely, rendering them unrighteous? A critical distinction exists between an act of situational weakness and a formal change of allegiance. In a military context, a loyal soldier may stumble, panic, or fail an objective, but they do not defect to the enemy camp. Abraham and David failed grievously in their behaviour, but they never abandoned the covenant to serve the gods of the surrounding nations. Their fundamental orientation remained fixed toward the Lord. When confronted with their deep sin, they did not flee His presence or renounce His sovereignty; they threw themselves entirely upon the mercy of their King (cf. Psalm 51). Pistis allows for the reality of human brokenness, but it completely excludes a relocation of loyalty.
The Cross: How Were the Ancients Saved?
One of the most persistent questions in biblical theology: If Jesus died for sin at a specific point in human history, how were people like Abraham, Moses, David, and Noah saved before the incarnation occurred? Were they saved by a separate system? Did they earn salvation by keeping the Mosaic Law or offering animal sacrifices? The author of the letter to the Hebrews dismantles this assumption:
The Levitical sacrificial system was never a cosmic transaction that paid the debt of sin; it was a pedagogical shadow and a prophetic placeholder. The sacrifices functioned as an ongoing show that maintained the covenant relationship by visualising the immense gravity of sin, while simultaneously pointing forward to a definitive resolution that livestock could never achieve.
The Faith of Abraham and David
Salvation has always been operational through grace via pistis, completely independent of the timeline of the law. Genesis 15:6 demonstrates this clear principle centuries before the tabernacle or the priesthood ever existed: "Abram believed the Lord, and He credited it to him as righteousness". The Hebrew text reveals that Abraham's pisteuo (translated as "believed") was an act of leaning his entire existence upon the stability of God's promise. His faith was a physical direction — leaving Ur, walking into the unknown, and staking his entire lineage on a future seed that God had guaranteed. Centuries later, King David — though living directly under the jurisdiction of the Mosaic Law — fully recognized that his personal salvation did not rest upon ritualistic performance. Following his moral collapse, he wrote:
David understood that forgiveness was an unearned gift of divine grace, accessed exclusively through a heart of broken, loyal surrender, not a mechanical transaction mediated by the blood of animals.
How can Old Testament saints be saved by the same faith as New Testament Believers if the cognitive content of their knowledge was radically different?
Abraham did not know the name of Jesus of Nazareth, nor did he possess any comprehension of a Roman crucifixion. If pistis requires explicit cognitive awareness of these historical gospel facts, their faith cannot be identical to ours. The object of faith has always been identical, even though the degree of historical revelation differed across time. The object of faith is the covenant-keeping God who promises redemption. In Romans 3:25, the Apostle Paul untangles this chronological divide, explaining that God displayed Jesus as a propitiation to demonstrate His righteousness, because in His divine forbearance He had passed over sins previously committed. The Greek term for "passed over" (paresis) implies a temporary reprieve — holding a debt in abeyance until the precise moment of historical settlement at Calvary. The ancients looked forward to the ultimate fulfilment of God's covenant promises (the shadow); modern Believers look backward at the concrete historical execution of those promises in the person of Jesus (the substance). The historical anchor for both groups is exactly the same cross. Abraham trusted that God would provide the ultimate lamb (Genesis 22:8); modern Believers trust that God has provided the Lamb (John 1:29). The volume of revelation progressed through time, but the character of the God being trusted — and the requirement of loyal reliance on His word — remained completely unchanged. When Hebrews 11 catalogues the ancient heroes of faith, it deliberately highlights their historical endurance through immense suffering. They were mocked, sawn in two, and destitute (Hebrews 11:36-37). The chapter closes with a striking structural observation:
Their faith was vindicated not because they lived to see the historical life of Jesus, but because they absolutely refused to walk away from the God who had promised Him. They remained standing. The cross of Jesus reaches in both chronological directions: forward to contemporary Believers, and backward to every ancient believer who trusted the character of God before the incarnation. No human being has ever been saved apart from Jesus. Some trusted the Saviour who had already come, while others trusted the Saviour who was promised, but every single person who is redeemed is saved by the exact same grace, through the exact same pistis, because of the exact same cross. Faith was never about how emotionally convinced you are; it has always been about where your allegiance is planted, and whether you are still standing there when it costs you everything.
