You may recall what the Word of God says about the fall of the angels who rebelled, along with Lucifer, against the Almighty God.
As to this salvation, the prophets who prophesied of the grace that would come to you made careful searches and inquiries, seeking to know what person or time the Spirit of Christ within them was indicating as He predicted the sufferings of Christ and the glories to follow.
It was revealed to them that they were not serving themselves, but you,
in these things which now have been announced to you through those who preached the gospel to you by the Holy Spirit sent from heaven—things into which angels long to look.1 Peter 1: 10-12
Grace is a deep fascination and mystery to the angels. The only thing that the angles have seen is that wrath of our God toward those who rebel. The mystery deepens with the totality of what our God has done for us. It is wildly out of every expectation in the heavenly realms.
God bridged such a huge gulf in His gift to mankind.
Lovingkindness and truth have met together;
Righteousness and peace have kissed each other. Psalm 85:10
The bare truth is that we too have rebelled. The gulf between our rebellion and God's love is astronomical. Scripture compares our righteousness or filth, stinky rages yet God has joined together righteousness and His peace. He has connected, in the heavenly realms, truth and His love.
Things so foreign to each other yet God found a way to meld the disparity together. This mystery is confounding to the created beings that surround God's throne.
But Jesus said, “ The things that are impossible with people are possible with God.” Luke 18:27
Jesus told us that God does impossible things. We just fail to believe Him!
Sunday after Sunday, week after week, year after year God's redeemed gather together each week for what we call "worship services". Do you think, from what you experience each week, that God's people really understand the deep, deep mystery of what even the angels long to understand?
Our worship should be wild! We should be blown away about our God to the point that we couldn't stand sterile singing called "worship" and passionless messages called the "good news"!
We have little control over others but we do have control over ourselves. Allow God to open up His marvelous mysteries to you and prepare yourself to go before His throne!
