Why is confessing Jesus as Lord important for Christians?

Confession of Jesus as Lord is not merely a verbal declaration; it signifies a deep-seated belief that transcends mere intellectual agreement. As Romans 10:9 states, one must confess with the mouth that Jesus is Lord and believe in the heart that God raised Him from the dead to be saved. This act of confession indicates that the individual recognizes and acknowledges their own sinfulness and agrees with God about the nature of Christ and His work in salvation. It is an expression of allegiance to Him, moving from a superficial profession to genuine faith. Meaningful confession also serves as a public affirmation of one's commitment to follow Christ, especially in baptism.
