Ean is the primary Greek conditional conjunction for third-class conditions — conditions that are possible or probable in the future. It combines ei (if) with the particle an. It appears hundreds of times in the New Testament, particularly in conditional promises and warnings that hinge on human response.
The theology embedded in ean is the theology of conditional covenant and human responsibility. Many of Scripture's greatest promises are framed with ean: 'If you confess with your mouth…' (Romans 10:9), 'If we confess our sins…' (1 John 1:9), 'If anyone loves me, he will keep my word…' (John 14:23). This does not undermine grace — God sovereignly enables the condition — but it preserves the genuine reality of human response and responsibility. The conditional frame invites active faith, repentance, and obedience rather than passive presumption.
