Why is belief in Christ important for Christians?

Belief in Jesus Christ is central to Christian faith; it is the means by which individuals enter into a saving relationship with God. Jesus states in John 3:18 that those who believe are not condemned, whereas those who do not believe are already in a state of condemnation. This underscores the transformative power of faith, which leads to spiritual regeneration and the inheritance of eternal life. Furthermore, belief shapes the believer’s identity and assures them of their position in Christ, fostering a life lived in obedience and joy rooted in the grace they have received through faith.
