Most people assume that John 6:57-58, is Jesus' hardest teaching. That's not true for me. There was a time when I didn't believe that the Eucharist was really Jesus' true presence, but when I thought about it, I realized that Jesus wouldn't lie. And the thought of seeing Jesus in heaven, and telling Him that I thought He was kidding, or being poetical, or worse--just plain lying, made me gulp down any unbelief. Now I need His Food and Drink daily. It's my life blood. But that's a different story.
What I find hard to see, is God in my fellow man. Genesis 2: 27. I find that to be the hardest of Jesus' teachings. I know I'm supposed to see something of God's glory in each person. But some poor souls don't even offer a glimpse of God's image. Sometimes they deliberately choose not to. What do I do in that case? Pray for them.
Pray for me.
