Why is calling on Christ important for Christians?

For Christians, calling on Christ signifies an ongoing relationship that acknowledges His lordship and the necessity of His grace. As illustrated in John 1:12, those who receive Christ have been granted the right to become children of God, which inherently involves calling upon Him. This act of calling is not a one-time event but an expression of faith that continually seeks His mercy and acknowledges our dependence on Him. Calling on Christ is essential in our Christian walk, serving as a response to His work in us and affirming our need for His guidance and strength.
