There was a famous mathematician in the seventeenth century named Blaise Pascal. When asked why we pray for things, Pascal said, "Prayer is one of the ways that God chose to share His infinite power with us."
Just as God's gift of intelligence gives each one of us power, His gift of prayer also gives us power. In other words, God set up the universe in such a way that we can influence it not only by our intelligence but also by our prayer.
Not every person can influence human affairs by the power of his or her intelligence. But every person can influence human affairs by the power of prayer that God shares with us.
In the gospel today, the disciples asked Jesus to teach them to pray. Jesus tells them the Lord's Prayer and he teaches them about praying persistently. In the same way, Jesus teaches us to pray persistently; to continue to turn to the Lord in prayer, asking for His guidance.
God has made us more than spectators to His creative power. He has given us a share in it. This is part of what it means to be made in the "image and likeness" of God.
Sincerely in Christ,
