“For since the world began, no ear has heard and no eye has seen a God like you, who works for those who wait for him!” Isaiah 64:4 NLT
The expression putting God to work means God has put Himself under the law of prayer and committed Himself to answer prayers.
Prayer moves God to do works among people in His own way which He may not do if prayers were not made
In reality, the denial of prayer is the denial of God Himself. God, His Word, Holy Spirit and prayers are inseparable that they can never be divorced.
Prayerlessness leaves man as the mere creature of circumstances, at the mercy of blind fate, and without help of any kind from God.
Prayer puts God to work in all things prayed for.
Shalom!
