The Spirit is the only way to completely conquer our sins. God changes us in ways we can’t change on our own. Romans 8:13: “For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live.” This is one of the great truths of the gospel. You don’t have to change on your own! You don’t have to do any of this on your own. Our transformed lives are the product of God working in us through his Spirit. Without the Spirit, our lives will not be transformed.
First, think of God the Creator and sustainer of all. Think of One who has unlimited awareness. Not a sparrow dies without Him knowing. The hairs of our heads are numbered.
