Why is calling on the Lord important for Christians?

For Christians, calling on the Lord is an essential act of faith and submission. It means recognizing our inadequacy and turning to God as our sole source of salvation. This calling involves pleading the name of Jesus, which signifies a union with Him and a trust in His redemptive work. As understood in Romans 10:13, calling upon the Lord is not just about verbal acknowledgment; it requires a heartfelt plea, brought forth by the Holy Spirit's work in us. This deep act of humility and reliance showcases the essence of our faith and reliance on God’s grace for our salvation.
