The Lord came to this world to give salvation and eternal life to those who believe wholeheartedly in the gospel of the water and the Spirit. The Lord did not come to this world to call people who thought they do not commit any sins and those who try to live a holy life in their own strength. Rather, the Lord came to this world in order to call and give true salvation to all those who could not keep the Law of God properly. We must believe that the Lord has came to call such people who are lacking, weak, and do not have much righteousness of their own, and we must also believe that He has blotted out all their sins.
We always need the grace of the Lord who came to this world and took up all our sins upon Himself once and for all by receiving the baptism from John the Baptist. We always need that grace of salvation that was accomplished by the Lord who received the judgment on the Cross because He had taken all our sins upon His flesh by being baptized by John the Baptist. Why is it like this? It’s because we humans commit sins everyday because we are lacking. You and I need the Lord’s grace everyday.
