Paul said in I Corinthians chapter 11 verse 23... 'For I have received of the Lord that which also I delivered unto you...'
We need to receive this today as from the Lord. Knowing what He did for us. To discern the Lord's body is to know that He provided for our healing. Isaiah chapter 53 verse 5 reads...'He was wounded for our transgressions, He was bruised for our iniquities, the chastisement of our peace was upon Him; and with His stripes we are healed.'
Continuing in Corinthians chapter 11 - The Lord Jesus the same night in which He was betrayed took bread:
And when He had given thanks He brake it, and said, take, eat, this is my body, which is broken for you: This do in remembrance of Me.
