Seeing you have purified your souls in your obedience to the truth through the Spirit in sincere brotherly affection, love one another from the heart fervently:

 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.
