If you have a desire to lead a Bible study, consider this desire to be a gift from God. "Delight yourself in the Lord and he will give you the desires of your heart" (Ps. 37:4). God never gives you a desire to do a task for Him without providing all you need to accomplish it. Your most important qualification for this role is a sense of dependence on the Lord for His perfect provisions.

Lorne Sanny said, "Prayer is the battle; witnessing is taking the spoils." It's just as true to say, "Prayer is the battle; leading a small group is taking the spoils." You lead with more confidence if you have prayed until you are trusting God to do His work in the class. Through prayer you gain sensitivity to the Holy Spirit so you can allow Him to guide the discussion according to the needs of the group.

If the truths you share have only reached your intellect, they will likely only reach the intellect of those in your group. But if the truths have reached your heart and changed your life, then there is a great chance they will reach their hearts and be life changing for them too.

Rely upon the Lord to be the teacher, because the Spirit must teach spiritual truths. Isaiah 55:10 promises that the Word will be "seed to the sower, and bread to the eater" (KJV). Your role is simply to sow the seed. As you do, God promises to provide the miracle of turning it into bread for those who receive it. Before every group meeting, ask God to provide spiritual bread for each one coming.
