The Christian life lived before the unbeliever prepared them to hear the truth of God's Word. Then the non-Christian was given the opportunity to hear the truth. In some cases, the one who brought the non-Christian to me for study never said a word. If you don't feel comfortable leading a friend or loved one in a Bible study, ask along someone whom you trust who has a good working knowledge of the Bible. It doesn't have to be the preacher.
Some people feel intimidated by preachers.
If you believe that to be the case, ask one of your elders or deacons. As I have said before, so say I now again- nothing would please me more than to fill up the evening hours in personal Bible studies set up by my brethren. Many Christians are under the impression that they do not have enough time to learn the scriptures and use them effectively. I believe if everyone will be honest in the previous evaluations, everyone will see that we do have time to read and study the Bible each day.
