This image by J. Tissot shows Jesus Christ walking with Simon Peter, His apostle, on the seashore after they had just had a miraculous catch of fishes. It is the third time Our Lord has visited the apostles after He had risen from the dead.
"When therefore they had dined, Jesus saith to Simon Peter: Simon son of John, lovest thou me more than these? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs." -JN 21:15
