Why did Jesus allow the betrayal by Judas who sold him for 30 pieces of silver?

Jesus knew that Judas was going to betray him, but he allowed it so that God’s plan could be fulfilled. So too, we must endure when we go through various trials, which is the testing of our faith, our belief that God will turn them around for our good. Jesus triumphed over betrayal, denial, persecution, abuse, death and the grave, and he did it so that we could have faith, to believe and trust him when we too face the same; confident, that we too will overcome. Praise the Lord!
