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: (20) Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
The last thing Jesus told his disciples was that I am with you. Even though he told them to go, teach, and baptize, they would not be alone. He promised them that he would be with them,no matter where they went.
He offers that same promise to us. As we get up and go, teach and baptize we should always remember that God and Jesus is with us no matter where we go.
