Teaching them to observe...

... At that time, Jesus said to his disciples, All power is given to Me in heaven and in earth. Going, therefore, 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 behold I am with you all days, even to the end of the world.

~ Matthew 28, 18-20
