Paul Tripp’s “5 Biblical Principles For Becoming A Better Friend” was mentioned in this lesson, particularly the C.S. Lewis quote at the end:
“When I have learnt to love God better than my earthly dearest, I shall love my earthly dearest better than I do now. In so far as I learn to love my earthly dearest at the expense of God and instead of God, I shall be moving towards the state in which I shall not love my earthly dearest at all. When first things are put first, second things are not suppressed but increased.”
