And so we worry that we maybe spiritually or morally inferior. We are being tempted because we are worthy of being tempted by the devil. Temptation rarely comes to us in clear cut decision between good and evil, but it comes to us shrouded in goodness, in attractiveness and in logical way for us to choose between easy and hard way. Only way to discern and resist temptation is to have a faith in Jesus. We can defeat it because Christ who showed us the way is living in us.
Transfiguration literally means a change in appearance.
If you spend 40 days and 40 nights alone, you get to know that person real well. In addition, Moses was soaked in the light, love and peace because God is light, love and peace. When we spend time with God ourselves, we too will soak up His light, love and peace but we may not notice it, but when we stand in this dark world, we would shine. We need to shine, not for our benefit or for our selfish reasons, but for the benefit of others, just like Moses and Jesus have shown us. We live in a midst of dualism.
