Apostasy refers to the abandonment of the true faith by someone who once professed belief in Christ.
In the Christian context, apostasy describes a situation where an individual who previously professed faith in Christ ultimately renounces that faith. This concept is addressed in 1 Timothy 4:1 and illustrated in 1 John 2:19, where individuals depart from the faith not because they were genuinely saved and then lost, but because they were never truly part of the faith community. True believers are marked by an enduring faith in Christ, as salvation is grounded in God's grace rather than individual merit. Therefore, apostasy reveals the peril of false professions and the necessity of examining oneself to ensure a genuine relationship with Christ.
