If you are a Christian you have the Spirit of Christ (the Holy Spirit) living within your mortal body. The Spirit indwells your mortal body through YOU the spirit living in that mortal body. In Romans 6, Paul speaks of your body as a mere instrument….not in control but yielded by your choice to righteousness. Through that Indwelling Spirit, sin shall not have dominion over you. If you have issues with easily besetting sins, when you see the Truth of what the Finished Work of the Cross has done to make you the dwelling place of God’s Spirit, those issues will be settled. You will have the joy of growing up into Christ in all things.
