Why is belief in Christ important for Christians?

Belief in Christ is the means through which individuals receive salvation and forgiveness. John 3:36 states, 'He that believeth on the Son hath everlasting life,' emphasizing that faith in Christ grants eternal life while those who do not believe face God's wrath. Paul elaborates on this in Romans 10:9, stating that if we confess with our mouth that Jesus is Lord and believe in our hearts that God raised Him from the dead, we will be saved. Believing in Christ is not only about intellectual assent but involves trusting Him fully as our Lord and Savior, which is essential for experiencing the grace of God and assurance of salvation.
