“Jesus took with him Peter and James and John, and led them up a high mountain apart, by themselves. And he was transfigured before them.” (Mark 9:2)

Peter became so excited for witnessing Jesus’ transfiguration, and said to Him, “Rabbi, it is good for us to be here.”

Not long after that, just before Jesus was crucified, He was bleeding and suffering; only these three apostles were beside Him at that time. Therefore, it is apparent that Jesus’ transfiguration is a preparation for the three apostles for the tests that lie ahead of them.

However, no matter how much preparation Jesus was offering these three apostles, they still fell asleep at Jesus’ loneliest and most painful moment. Thus, He exclaimed “The spirit is willing, but the flesh is weak”.
A lot of times, we are enjoying peace and joy on our spiritual journey. However, when the painful moment arrives, Jesus may say the same thing to us as He has said to the three apostles, “So you could not keep watch with me for one hour?” In other words, Jesus is always with us, even during our painful times.
