Both are true. The sovereign life of Christ is lived through you, but you need to submit your will to allow Him to live through you. God sovereignly motivates your will, but it has to be activated. Principles of obedience 1. The Lord Jesus Christ.
Obedience is a mark of conversion.
If you're God's child, you'll obey what He says. When you obey, you are telling God that He is in control and that you're in submission to Him. If you know clearly that God wants you to do something, and you don't do it, then you have replaced God as the controlling authority in your life. Yet that's what goes on most of the time. You have that choice.
