Jesus gave up his life. The single greatest sacrifice a man may make and it was for the sake of sinners.
The best example of Jesus that might inspire Christians facing persecution today would be his arrest, trial and crucifixion. It is shown in the garden of Gesthemane that Jesus did not want to endure the pain of crucifixion or experience the burden of the sins of the world. Thus Jesus prayed as Christianity teaches one should do, when feeling "distressed and troubled." However, God required of him this sacrifice and Jesus was obedient to God, even though he was being asked to do something, which he did not want to do and which would cause him pain. Jesus trusted in God and so did as he was asked; although as a human he was weak and needed reassurance he prayed. This is an example which could help Christians facing persecution to keep their faith.
Jesus faced opposition almost everywhere he went. Yet, Jesus still tried to spread the word of God and do good on earth. A prime example is that of the Pharisees trying to get Jesus to commit treason, asking whether they should pay taxes to Rome or not, so that he could be arrested but Jesus answered honestly, bearing in mind his faith. "Give to Caesar what is Caesar's and to God what is God," Jesus thus could be an example to Christians facing persecution, that one should stand up and answer with your faith and God will be with you.
Jesus taught, "have faith in God... I tell you the truth that, if anyone says to this mountain, 'Go throw yourself into the sea,' and does not doubt in his heart but believes that what he says will happen, it will be done for him."...
