Praise the Lord for His Vicarious death.,. He died for us to save in this world of sin. I think the point of this song is that in ourselves, we can do nothing. We are nothing before God. That's why we need Him cause He is everything to us! And with God We can do everything.
So you must lay down all your anxiety, problems etc. To the Lord.
Imagine. The Lord had gone many processes like he became a man. And live a life of human. And he was crucified, died and ascended in the heavens and became a life giving Spirit! And after 3 days He resurrected from the dead. From the very high God he pass through many processes He humbled Himself to reach us and He became the Life Giving Spirit for us to receive Him! How can we receive the Lord!
It is just by calling on the name of the Lord be open to him and say " Lord Jesus ! I want to receive you" you must be baptist into the name of the Lord not into tne name of the name of denominations. But in the Lord's name. To call upon the name of the Lord you must. Contact Him in your prayers to call the name of the Lord is like this " Oh! Lord Jesus! And say to Him that you love Him! Praise Him to the uttermost!
