Jesus not only prepares us to endure persecution for His sake, He endured persecution for our sake. In Matthew 26:47-27:31, we see Jesus face persecution from cowards who had the opportunity to honor Him, but chose instead to participate through:
Betrayal (Judas)
Abandonment (Disciples)
Denial (Peter)
Abstaining (Pilate)
Mocking (Soldiers)
Yet, ultimately we must realize that we are as responsible as these cowards for the persecution and death of Jesus - through which God has brought salvation to all who receive and rest in the risen Christ!
