Comforter

 

John 14:16 (KJV)

And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;

Expedient

 

John 16:7 (KJV)

Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.

God with us

 

Matthew 1:23 (KJV)

Behold, a virgin shall be with child, and shall bring forth a son, And they shall call his name Emmanuel, which being interpreted is, God with us.

 4Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. 

Psalm 69:29
