Cornelius was an unsaved Gentile but a discerning man of prayer. He saw through the futility of pagan prayer rites which he learned as a child and from his cultural background. But he learned to pray to the true God of heaven.
In answer to this unusual expression of faith outside the covenant people, God dispatched a special angelic messenger who informed Cornelius how he might be acceptable before God.
He was to send for Peter who became God’s instrument of preaching the gospel of Jesus Christ to Cornelius. Very definitely this story teaches that God will both hear and answer the sincere cry of every seeking heart.
