He who has pity on the poor lends to the Lord, and that which he has given He will repay to him. Proverbs 19:17 (AMPC)
Pitying the poor goes beyond just feeling sorry for them or rehearsing their sorry state. It is seeing yourself in their shoes and being moved with empathy to do something to alleviate their condition. It is doing all you can to help them. It is sharing with them what you have, what you can.
Jesus pitied and helped the poor by first proclaiming the good news to them. Luke 4:18.
He helped the poor by feeding them. One time He fed 5,000 men besides women and children with five loaves and two fish then again another time He fed 4,000 men besides women and children with seven loaves and a few fish.
The poor aren’t only those lacking money or material possessions. The sick, the weak, the oppressed, the forsaken, the rejected, the lonely are all poor – they lack something good and beneficial. They all are in need. When we minister to these we are doing it to the Lord and His reward for us is already with Him.
