Woe to you who seek joy in the world, for you will mourn. Woe to you when you depend on what others think of you, for you will not find the kingdom. I say to you that hear. Jesus was always trying to get people to open their eyes and their ears. He is not referring to their physical but their spiritual faculties.
Hearing is both physical and spiritual.
When you look at a person you are using your spiritual eyes. When you sense their presence and are feeling something you are touching the untouchable, Once you are using your spiritual faculties, then all we need to do is sense the Presence of God who is closer to use now than any thing or any one else. When you are in His Presence and feeling the Love of God which will not let you go, and the Peace of being in the Presence of Jesus and the Joy being with the Spirit, you will see things differently than when you are feeling unloved, unhappy and insecure. You will be able to love your enemies, want to share with those in need and find the power to forgive those who offend you. This passage is not as much about Jesus being transfigured, or the apostle s reaction to it.
