Matthew 7:21-23
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' And then will I declare to them, 'I never knew you; depart from me, you workers of lawlessness.'

A friend used to say to me, "If Jesus is not Lord of all, He is not Lord at all." Let us investigate every area of our lives and test whether we really have surrendered to His grace and mercy. The children of God have been crucified with Christ, and it is no longer they who live, but Christ who lives in them.

If Jesus is not Lord of all (of you), 
  He is not Lord (of you) at all.
