First of all, the bible tells us to (See verse below). This is not a suggestion! Secondly, it should not be out duty, but out of devotion. This should be a natural outpouring, from the fruit of the spirit, working in us, and a reflection of the Gospel, our own understanding of Christ’s work, (not our own), in our lives.
So then, while we have opportunity, let us do good to all people, and especially to those who are of the household of the faith.
