Why do we need to believe in Christ for salvation?

Belief in Christ is essential for salvation as it acknowledges and accepts the finished work Christ accomplished on the cross. While salvation is wholly a work of God, faith is the instrument through which we receive grace. According to John 3:16, belief in Christ assures us eternal life, not based on our merit but on His sacrificial atonement. This faith is a response to God's call and is not a work in itself, but an acknowledgment of our dependence on His grace and a trust that He will fulfill His promises to save those who come to Him.
