And what was that Jesus told us to eat?
"Then Jesus said unto them, 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; and I will raise him up at the last day.
For my flesh is meat indeed, and my blood is drink indeed.
He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him." John 6:53-56
The disciples ate the fish, but perhaps they needed to feed the sheep and lambs with what God supplied. What does that take? What are we to feed others?
"Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
This is now the third time that Jesus showed himself to his disciples, after that he was risen from the dead.
So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.
He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep." John 21:13-17
