How Christ Commanded Baptism to his Disciples

Matthew 28, verses 18 to 20: "And Jesus came and spoke to them, saying, All power is given to me in heaven and in earth. Go therefore, and teach (or make disciples of) 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 always, even to the end of the world. Amen." Mark 16, verses 15 and 16: "And he said to them, Go into all the world, and preach the gospel to every creature. He who believes and is baptized shall be saved; but he who does not believe shall be damned."
