We can really be able to do nothing of owns selves as children of God. The scripture says its not by power and it's not by might of our own that we can reach God's call and purposes for our lives as we go about our endeavour. Not by power is a cry out to God for His Spirit to help us with the grace to reach our goals and His purposes for our lives. This mid tempo of this song and the melody will lift the soul of any believer and cause all to solely depend on God for every need we have.
