Prayer begins with God. The only way to have victory is to pray in faith. Though we profess to know the Lord Jesus as our Saviour, we really have no Christian life without the Bible and prayer; we only exist. As we exalt His name and think on His greatness, we are encouraged to pray.
Our Heavenly Father has everything we need. His Son Jesus Christ is interceding for us at His right hand. We cannot separate prayer from our Christian lives.
