“In the outpouring of the Holy Spirit, in the house of Cornelius at Cæsarea, we have another testimony to the wondrous interdependence of the action of prayer and the Spirit, and another proof of what will come to a man who has given himself to prayer. Peter went up at midday to pray on the housetop. And what happened? He saw heaven opened, and there came the vision that revealed to him the cleansing of the Gentiles; with that came the message of the three men from Cornelius, a man who “prayed alway,” and had heard from an angel, “Thy prayers are come up before God”; and then the voice of the Spirit was heard saying, “Go with them.” It is Peter praying, to whom the will of God is revealed, to whom guidance is given as to going to Cæsarea, and who is brought into contact with a praying and prepared company of hearers. No wonder that in answer to all this prayer a blessing comes beyond all expectation, and the Holy Ghost is poured out upon the Gentiles. A much-praying minister will receive an entrance into God’s will he would otherwise know nothing of; will be brought to praying people where he does not expect them; will receive blessing above all he asks or thinks. The teaching and the power of the Holy Ghost are alike unalterably linked to prayer.”
