One needed a place of safety a sanctuary that affirmed the individual as a child of God. That makes sense and Paul challenges his readers to become communities of love, mutual support, and affirmation. If they are thirsty, give them something to drink . Love is not exclusive, and sometimes it requires a Herculean effort. Paul takes it much further.
Love is manifest in actions.
Love is active. These are active words. Our lives need to embody the words we proclaim. My favorite quote is from Handy. He was speaking to a missionary who was in a bit of despair.
