"Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven." Matthew 16:17
One day everything will be revealed. Paul wrote, "Now we see through a glass darkly but then face to face." (I Corinthians 13: 12a)
We look forward to having some of the pieces of the puzzle put into place.
In order to save money, a college drama class purchased only a few scripts of a certain play and cut them up into the separate parts. The director gave each player his individual part in order and then started to rehearse the play. But nothing went right. After an hour of missed cues and mangled sequences, the cast gave up.
At that point, the director sat the actors all on the stage and said: "Look, I'm going to read the entire play to you, so don't any of you say a word." He read the entire script aloud, and when he was finished, one of the actors said: "So that's what it was all about!"
And when they understood the entire story, they were able to fit their parts together and have a successful rehearsal.
C. S. Lewis once said that the most frequently spoken word in heaven would be, "OH." As in, "Oh, now I understand." Or, "Oh, now I see what God's plan was." Or, "Oh, now I see the reason for the trial I went through."
In this world, however, we walk by faith, not by knowledge. But one day it will be revealed to us. We will be in the presence of the Father and the Son and the Spirit. How can we be in the presence of all three at the same time? Paul says in another place, "I know the one in whom I have put my trust, and I am sure that he is able to guard until that day what I have entrusted to him." (2 Timothy 1:12)
There are some answers that are too large for our brains to contain. But our greatest need is not understanding, but trust that God is with us. God is with us and will be with us until that day comes when all will be revealed.
