'Peter remembered the word of the Lord' - Perhaps it was familiarity or because so much had been said that Peter took little heed of Jesus` warning. Yet whatever it is Jesus says we do well to remember.
For some it is on a mother's knee or in a godly home: others are suddenly confronted with the Lord addressing them.
The words of the Lord are never idle or trivial. In Peter's case the recall of them served to fill him with remorse at his abject failure.
But the Lord did not merely forewarn Peter that he was to deny his Master: He also assured him of prayer support and conversion.
God is gracious when He calls things to our mind, though the memory may at first be painful.
