The Great Commandment
Matthew 22:36-40

Master, which is the great commandment in the law?  Jesus said unto him, Thou shalt love the Lord thy God with all they heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbor as thyself.

The Great Commission
Matthew 28:19-20

Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world.  Amen.
