Mathematicians talk about simultaneous equations. They are called simultaneous equations because the equations are solved at the same time. Well, in spiritual parlance, we can talk of simultaneous visions. I think this plays out beautifully in the book of Acts of the Apostles.
There is a similarity of context between the vision of Cornelius and the trance of Peter. The centurion was praying about 3 O’ clock in the afternoon when he saw the vision of an angel who advised him to send for Peter. In Peter’s case he was also praying, only by 12 noon, when he had a trance. It is easy then to conclude that the hour of prayer is a moment for visions and revelations of God. It is not in all cases of praying that we have pictorial vision or trance. But we can be sure that every time we pray, God make impression upon our heart; and that may be the critical guidance we need for the season. Prayer is indeed a key that unlock the door to the spirit realm.

“God’s plan for one life may be inseparably connected to His operations in another life…God has to bring into our life necessary persons to help interpret the vision He has given to us.”

Peter’s trance also gives insight to the workings of God. Shortly after Cornelius had his vision, God gave Peter his. Without the visitation of God to Peter that of the Centurion would be meaningless. One vision resonates in another. The lesson is that God’s plan for one life may be inseparably connected to His operations in another life. We see this pattern in Saul, later Paul. The visit of the angel to Ananias was vitally important if the vision Paul had on the way to Damascus would make full meaning. God has to bring into our life necessary persons to help interpret the vision He has given to us.
