For God, who commanded the light to shine out of darkness, has shined 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 of God, how turn you again to the weak and beggarly elements, to which you desire again to be in bondage?
And 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, that you may live.
Seeing you have purified your souls in obeying the truth through the Spirit unto sincere love of the brethren, see that you love one another with a pure heart fervently:
Brethren, I write no new commandment unto you, but an old commandment which you had from the beginning. The old commandment is the word which you have heard from the beginning.
If a man says, I love God, and hates his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen?
