Is Jesus Christ living in us? That was the goal of the Apostle Paul. Surely it should be our goal as well. Paul wrote:
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. (Galatians 2:20)
This truth of Christ living in me is also seen in the Gospel of John:
He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever. (John 6:56-58)
In the Book of Revelation we read:
Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. (Revelation 3:20)
Jesus is not speaking to unbelievers here, but to the Church. He wants to sup with us. The Holy Communion of the Lord’s Supper has been given to us so that we may participate in the heavenly banquet with Jesus while on this earth.
The importance of these verses cannot be overlooked. Thus we see that Communion is not optional for the Christian disciple. It is vital and should be partaken as often as possible, preferably on a daily basis. (See Eucharist Theology and Home Communion.)
