Faith and prayer are powerful in the hands of the Christian, and their effect is not to be underestimated. We have spoken about praying within the will of God, but simply asking for something without the faith that what we have asked for will be given to us is not enough. We must believe, and have faith that God intends to provide that thing. We need to trust completely in His Word and provision. Have you ever prayed for the Lord to do or provide something, and then wondered if He had heard you, or if He would actually do so? This is a lack of faith.
