The Greek epeide (Strong's G1897) is a causal/temporal conjunction meaning 'since,' 'inasmuch as,' or 'when.' It combines epi (upon) with eide (seeing/since) to introduce a clause that gives the reason or occasion for what follows. It appears in contexts where Paul and other New Testament writers ground their arguments in observable realities or established facts.
Epeide marks the logical structure underlying New Testament argumentation. When Paul writes 'since God's wisdom saw to it that the world through its wisdom did not know God, God was pleased through the foolishness of preaching to save those who believe' (1 Corinthians 1:21), the conjunction frames the entire theology of the cross as a response to human failure. This small word reveals the New Testament's intellectual discipline: divine action is always rational, always responsive to real conditions. The gospel is not arbitrary — it is the perfectly calibrated answer to humanity's demonstrated inability to reach God through wisdom alone.
