Acts 10:4 Cornelius stared at him in fear. “What is it, Lord?” he asked. The angel answered, “Your prayers and gifts to the poor have come up as a memorial offering before God.”
Cornelius was a man who gave to those in need and prayed for those in need regularly; now was the time God was going to answer him in a special way.
How many times do you lift up your prayers and wonder whether God is listening – I know I have been guilty of that in the past, but I know now God is always listening!
God send an angel in a vision to Cornelius to reach out to the apostles; and at the same time God gave visions to Peter to reach out to the Gentiles/Romans.
Don’t doubt God’s abilities; prayer in faith.
