Step #1: Messianic Application

We lift the cup in the right hand because the right hand represents the Messiah.

Exodus 15:6 Thy right hand, O LORD, is become glorious in power: thy right hand, O LORD, has dashed in pieces the enemy.

Psalm 44:3 For they got not the land in possession by their own sword, neither did their own arm save them: but thy right hand, and thine arm, and the light of thy countenance, because you had favour unto them.

John 12:32 And I, if I be lifted up from the earth, will draw all men unto me.
