Titus 2:11 says, "For the grace of God that bringeth salvation has appeared to all men"
This song speaks about the grace of God, Jesus Christ who brought us redemption through His death and resurrection. He is that Grace of God by whom man can become what God has destined him to become. We are declared righteous by grace through faith. Therefore it is not by works but by Grace. So that at the end, no man would boast but give all glory to the God of all Grace.
This is a reflection of that Grace that found me, made and saved and will do till the end.
