I've chosen him so that he will teach his sons and their families to follow the way of the Lord by doing what is right and good, so that I, the Lord, can do for Abraham what I promised.”
So whoever disregards the least important commandment, and teaches people to do so, will be called the least in the kingdom of heaven; but whoever practices and teaches the commandments will be called great in the kingdom of heaven.
So my dear brothers and sisters: be strong, stand firm, doing everything you can for the Lord's work, since you know that nothing you do in the Lord is wasted.
