It is God’s intention that NOW His manifold or multi-faceted wisdom should be made known by the church to the principalities and powers, or the angelic realm. In fact, we saw in 1 Pet.1:12 that angels desire to look into and understand the grace that has been revealed to us. Sure the angels can sing, “Holy, Holy, Holy” (See Isaiah 6:3), around the throne 24 hours a day, 7 days a week. But you’ll never hear them sing, “Amazing Grace, how sweet the sound, I once was lost but now I’m found!” How blessed we are that we can sing amazing grace, and join in with the angels too, in singing, “Holy is the LORD!”
