Dr. Wesley L. Duewel: There are thrilling biblical examples of agreement in prayer. When Moses faced the problems of disobedient, unbelieving Israel, he and Aaron repeatedly agree in prayer.
We first see it when the Amalekites attacked Israel at Rephidim. Moses, Aaron, and Hur climbed a hill, and Aaron and Hur upheld Moses' hands in prayer. (Moses and Aaron)
This action symbolized their agreement in prayer (Exod. 17:8-16). Moses reported afterward, "Hands were lifted up to the throne of the LORD"(v. 16).
Primarily, they were the hands of Moses, but united with Moses were the hands of Aaron and Hur.
At Kadesh-Barnea when Israel wanted to turn back to Egypt, "Moses and Aaron fell facedown" in prayer before the Lord (Num. 14:5).
When God was about to destroy the whole community of Israel who had rallied with Korah in rebellion, Moses and Aaron again fell facedown before the Lord (16:22). The next day (v. 45) and when Israel grumbled from thirst (20:6), we see them again on their faces agreeing before God.
During Jesus' ministry on earth we have no proof that His disciples ever agreed in prayer with Him. No doubt Christ often longed for such prayer, especially in Gethsemane (Matt. 26:38-45).
Most probably much of the ten days in the Upper Room were spent in united prayer. But as their prayer time continued, they most probably came to the place where they were united in the prayer of agreement for the promised Holy Spirit.
It may well be that the Spirit delayed His coming until the 120 were totally agreed in prayer (Acts 1:14; 2:1). Certainly in Acts 4:24-31 the now Spirit-filled Upper Room group was praying in agreement.
Peter and John prayed the prayer of agreement in Samaria (Acts 8:5-17), and many of the church missionary movement of Paul and Barnabas was launched through such a prayer meeting (13:2-3).
Though absent in body from the church in Corinth, Paul may have been praying the prayer of agreement with them (1 Cor. 5:4).
The Methodist Pentecost in London was obviously a time of prayer of agreement. Wesley's journal of January 1, 1739, records how he his brother Charles, George Whitefield, and more that sixty others were praying.
"About three in the morning, as we were continuing instant
in prayer, the power of God came mightily upon us,
insomuch that many cried out for exceeding joy, and many
fell to the ground. As soon as we were recovered a
little from that awe and amazement at the presence of
His majesty, we broke out with one voice, 'We praise Thee,
O God, we acknowledge thee to be the Lord.'
