Jesus taught that we need to take severe measures to keep us from sinning when we are tempted.
6 "If you cause someone who believes in me to sin, even if it is someone who is socially unimportant like this little child, God will severely punish you. If a heavy stone were fastened around your neck and you were thrown into the deep waters of the sea, people would consider that you had been severely punished. But God will punish you more severely than that if you cause someone to sin
Jesus taught that God is deeply concerned if even one person goes astray from him.
10,11 "Make an effort that you (pl) do not despise even one of these children. I tell you (pl) truly that since the angels live in heaven in the presence of my Father, they will report to him if you mistreat the children.18:10-11 Some Greek manuscripts add verse 11, ‘For the Son of Man came to seek the lost’.
