For God, who commanded the light to shine out of darkness, has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.
But now, after you have known God, or rather are known by God, how do you turn again to the weak and worthless elemental forces to which you desire again to be in bondage?
The Lord your God will circumcise your heart and the heart of your descendants to love the Lord your God with all your heart and with all your soul, so that you may live.
Since your souls have been purified by obedience to the truth through the Spirit unto a genuine brotherly love, love one another deeply with a pure heart,
Brothers, I am writing no new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word which you have heard from the beginning.
If anyone says, “I love God,” and hates his brother, he is a liar. For whoever does not love his brother whom he has seen, how can he love God whom he has not seen?
