It is God which worketh in you both to will and to do of His good pleasure. Philippians 2:13.
Yield up your will to the will of Jesus Christ; and as you do this, God will immediately take possession, and work in you to will and to do of His good pleasure. Your whole nature will then be brought under the control of the Spirit of Christ; and even your thoughts will be subject to Him.... You need to drink daily at the fountain of truth, that you may understand the secret of pleasure and joy in the Lord. But you must remember that your will is the spring of all your actions. This will, that forms so important a factor in the character of man, was at the fall given into the control of Satan; and He has ever since been working in man to will and to do of His own pleasure, but to the utter ruin and misery of man. But the infinite sacrifice of God in giving Jesus, His beloved Son, to become a sacrifice for sin, enables Him to say, without violating one principle of His government, “Yield yourself up to Me; give Me that will; take it from the control of Satan, and I will take possession of it; then I can work in you to will and to do of My good pleasure.” When He gives you the mind of Christ, your will becomes as His will, and your character is transformed to be like Christ’s character.—Testimonies for the Church 5:514.
