Therefore, prepare your minds for action,{Literally, "gird up the loins of your mind"} be sober and set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ--

 It is in the purpose of God that the Christian is called. It is by the work of the Holy Spirit that his life is hallowed towards God. It is by the sprinkling of the blood of Christ that he is cleansed from past sin and dedicated to future obedience to God.
