In this last portion of the letter to the Hebrews, Paul gives some sound Christian advice. There is nothing new in it but the sincerity of his teaching and how practical that teaching is, is what strikes me.
"Welcome the stranger for in doing so we could be welcoming angels," is a beautiful thought.
"Those in prison keep them in mind." With a thought like this about prisoners, Paul shows how nonjudgmental he is. There is no mention of the crimes that these prisoners have committed.
"Keep marriage undefiled." Marriage is one of only seven ways that Jesus chose to save the world; it is one of the sacraments and thus one of the way Jesus chose to save the world.
Then Paul tells us not to be greedy but to be content with what we have. We can teach ourselves to be content with our worldly goods. We can get by on enough. It is an attitude of mind, not needing all the extras.
And finally Paul assures us that God shall look after us for God has said, "I will not fail you or desert you."
"With the Lord to help me, I fear nothing; what can man do to me?" Paul carried this confidence even to his death. God never fails us, even when things look to be at their worst.
