Let mutual love continue. Do not neglect to show hospitality to strangers, for by doing that some have entertained angels without knowing it. Remember those who are in prison, as though you were in prison with them; those who are being tortured, as though you yourselves were being tortured. Let marriage be held in honor by all, and let the marriage bed be kept undefiled; for God will judge fornicators and adulterers. Keep your lives free from the love of money, and be content with what you have; for he has said, “I will never leave you or forsake you.” So we can say with confidence, “The Lord is my helper; I will not be afraid. What can anyone do to me?” Remember your leaders, those who spoke the word of God to you; consider the outcome of their way of life, and imitate their faith. Jesus Christ is the same yesterday and today and forever. (Hebrews 13:1-8, NRSV)
This passage is about putting ourselves in the place of the other.
Remember those who are:
Act like you are also in prison with them, being tortured with them, and keep all marriages undefiled.
Remember all people and look out for them.
