Yes, this mystery is Christ revealed. God had chosen Him to become a man, to know and experience the sufferings, helplessness, sin, pain and sickness; what it means to be human. And not only to know, but to bear, carry, take away, to erase; and then not only to take away, but to exchange, to give in place of, His life, His power, His authority, His glory, perfection and Oneness with God.
This was unheard of through the ages. This was so foreign to the laws of the heavens and the earth.
Yet, you and I have what the prophets had not, you and I have free access to what angels wondered at.
Let us remember this Easter what He has done and who we are because of Him!
1 Peter 1:10-12
Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care, trying to find out the time and circumstances to which the Spirit of Christ in them was pointing when he predicted the sufferings of the Messiah and the glories that would follow... Even angels long to look into these things.
1 Peter 1:20
He was chosen before the creation of the world, but was revealed in these last times for your sake.
