Matthew 14:28

‘And Peter answered him and said, “Lord, if it is you, bid me come to you on the waters.” '

On hearing Jesus' words, and no doubt recognising His voice, Peter, with his usual mixture of impetuosity and faith, called out to Him and said, “Lord, if it is you, bid me come to you on the waters.” His confidence in Jesus was such that He had no doubt that the One Who had given him the power to heal the sick and cast out devils could also enable him to walk on the waters that lay between Him and Jesus (in Hebrew ‘waters' is always plural). But he would only do it once he had the Lord's assurance that the ability would be given to him. Here was a remarkable indication of both understanding and faith, even if it did not last for long because his faith was insufficient.

‘The waters.' Peter was probably indicating by this the short stretch of water between the boat and Jesus.
