Judas deliberately betrayed his Master while Peter, in a moment of weakness, denied him with an oath and a curse. Judas' act was cold and calculated.
Peter, however, never meant to do what he did. He acted impulsively, out of weakness and cowardice. Jesus knew both the strength of Peter's loyalty and the weakness of his resolution.
He had a habit of speaking with his heart without thinking through the implications of what he was saying. The treachery of Judas, however, is seen at its worst when Jesus makes his appeal by showing special affection to him at his last supper.
John says that Satan entered into Judas when he rejected Jesus and left to pursue his evil course. Satan can twist love and turn it into hate.
He can turn holiness into pride, discipline into cruelty, affection into complacency.
We must be on our guard lest Satan turn us from the love of God and the path which God has chosen for us.
The Holy Spirit will give us grace and strength in our time of testing.
If we submit to Jesus we will walk in the light of his truth and love.
If we turn our backs on him we will stumble and fall in the ways of sin and darkness.
Are you ready to follow Jesus in his way of the cross?
