Believing in Christ is not just intellectually agreeing that He is Lord and Savior. True faith involves obeying His words (Lk 6:46-49).

We are saved by grace through faith, but faith without deeds is not true faith (Jas 2:14-20). Even evil spirits believe that Jesus is the Son of God (Mt 8:28-29; Lk 4:41), but their belief is not true faith (Jas 2:19-20). We cannot dismiss the necessity of baptism since baptism itself is an act of belief and faith in Jesus Christ (Mk 16:16; see Acts 16:30-33).
