We should no longer trust in ourselves and should not try to overcome sin. We are not able to overcome it. Rather, we should set our mind on the spirit. Romans 8:6 says, “For the mind set on the flesh is death, but the mind set on the spirit is life and peace.” Today the Spirit, who is the Spirit of life, Christ Jesus Himself, is one with us in our spirit. All day long we need to set our mind on nothing but our spirit. Our mind set on our spirit is life, and this life is the processed Triune God—the Father, the Son, and the Spirit, the consummation of the Triune God. Moreover, a person whose mind is set on the spirit walks according to the spirit (Rom. 8:4). We must learn to see these truths and learn to practice setting our mind on our spirit all the time. This is the experience of life which produces the growth of life.
To define the way to set our mind on the spirit is to yield to a temptation. Paul did not charge us by saying, “Set your mind on the spirit.” We do not need to make up our mind to do this. Faith stops our activities. Faith always praises God. The example of Joshua and Caleb in the Bible shows us what it is to believe. Joshua and Caleb were not the ones who overcame in Numbers 13 and 14; it was the One in whom they trusted. God did everything. They simply enjoyed what God did. In Joshua 3 they crossed the Jordan River, but it was God who stopped the water. They simply walked over.
Do not try to overcome your sin. Simply believe. Hallelujah! We are in Christ. Christ is our great I Am, and He is the Spirit of life. We have a Savior. If we do something for ourselves, we are attempting to be our own savior. We are declaring that we do not need Him. If we declare that we are wretched and hopeless and cannot do anything to rescue ourselves, then we are declaring that we need a Savior. (Experience and Growth in Life, Chapter 6)
