Prayer lets use see opportunities that we would otherwise miss, and creates opportunities that wouldn't have existing if we didn't pray. This is called intercessory prayer . Richard Lovelace in the book Dynamics of Spiritual Life notes that majority of the great mission and revival movements can be traced directly to a small group of people to covenant together to pray. If you need to be convinced how critical, and how effective prayer is, read Touch the World Through Prayer by Wesley L.Duewel, Zondervan, 1986. The Bible tells us that it is important to pray with our minds.
Information is fuel for effective prayer.
So besides a willingness to respond to the Lord we need content, we need something to pray about. Pray for yourself and your Christian friends, that you would be a good witness and have opportunities to share the Lord with others. If you know people who are missionaries, pray for them . If you don't know any missionaries, take some time to learn about the missionaries that your church supports. Peninsula Bible Church has a missions directory which will introduce the missionaries we support, and list some specific prayer points and a key contact who can give you more information.
