And Jesus came and said to them, saying, “All authority has been given to Me in heaven and one earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, even to the end of the age.”
Matthew 28:18-20 ESV
And he said to him, "You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and first commandment. And the second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.
Matthew 22:37-39 ESV
