Tax collectors and sinners were coming to Jesus to listen to what he had to say. The Pharisees and scribes complained about this saying “This man welcomes sinners and dines with them!”
(People also questioned why Jesus would bless small children.)
“Be careful that you don’t belittle young children. You need to know that their angels constantly see my Father in heaven. The Son of Man has come to rescue the lost.”
“Consider this, if one of you has a flock of 100 sheep, and one of them wanders away and gets lost, don’t you leave the 99 on the hillside to go find the one who wandered away? I assure you, if you find it you’ll joyfully put it on your shoulders and come home, calling your friends and neighbors together to rejoice with you that you have found your lost sheep. You’ll celebrate over that one sheep more than you will about the 99 that stayed. In the same way, your Father in heaven will celebrate more about one sinner who returns to Him than over the 99 righteous people who never turned away. It is not the will of your Father in heaven that anyone should perish.
