When you became a child of God, you were given all you need "in Christ" to become a spiritually growing believer. However, you are responsible to make a choice! Will you choose to use and apply God's principles to your life? The wonderful thing about being in submission and obedience to God's maturing process is that you will be changed! You don't have to worry about becoming mature. God does the changing! He will conform you to the image of Jesus Christ as you humbly surrender to His Holy Spirit and learn His Word.
