Jesus taught that the Father has life in Himself and has given to the Son that He also has life in Himself. This sets Christ apart from us. We most certainly do not have life in ourselves. But we access that life, that eternal and abundant life, through this bread and wine.
Jesus said, and indeed it was a hard saying, “Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood hath eternal life” (John 6:53).
