Romans 8:5 AMPC
For those who are according to the flesh and are controlled by its unholy desires set their minds on and pursue those things which gratify the flesh, but those who are according to the Spirit and are controlled by the desires of the Spirit set their minds on and seek those things which gratify the (Holy) Spirit.

You cannot harness your mind to the things of God. Your mind cannot be directed toward the Lord. Only the Spirit can control your thought life and your desires.

We often have trouble with wandering thoughts and wrong thoughts, but the problem is not in the mind. It is because we have not truly and totally surrendered to the dominion of the Holy Spirit. When He is given free reign, He is ABLE to control the mind and set its direction toward God’s will. Only the Spirit can handle this reckless mind of humanity!
