"I do not know this man," Mark 14:71.
That was Peter's sworn testimony. About Jesus. He cursed by the warm fire outside while soldiers slapped and spit on and beat on Jesus inside for testifying he was God's son. Yep. Jesus confessed to that crime in the tribunal of man. Maybe Peter just had a momentary lapse. Forgot that Jesus had called him to the gospel; that Jesus had healed his family; that he had fed him; that he had given him miraculous powers; that he had paid temple taxes for him; that he had shown him unspeakable glory on the mountain. That Peter earlier, amazed, confessed: You are the Christ, the Son of the living God! Forgot he had promised a few hours ago to have Jesus' back all the way. Yeah. That was probably it. Just slipped his mind. And heart.
Meeting a brother or sister today we pay very close attention to the truth of Jesus, our Lord. And together we give humble thanks for the One who never betrays us, but ever is faithful.
