Jeremiah 32:40–41 & Matthew 5:19

Jeremiah 32:40–41 

40 I will make with them an everlasting covenant, that I will not turn away from doing good to them. And I will put the fear of me in their hearts, that they may not turn from me. 41 I will rejoice in doing them good, and I will plant them in this land in faithfulness, with all my heart and all my soul. 

Matthew 5:19

Therefore, whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven.
