This is illustrated in the life of the famous author Mark Twain. Church leaders were largely to blame for his becoming hostile to the Bible and the Christian faith. As he grew up, he knew elders and deacons who owned slaves and abused them. He heard men using foul language and saw them practice dishonesty during the week after speaking piously in church on Sunday. He listened to ministers use the Bible to justify slavery. Although he saw genuine love for the Lord Jesus in some people, including his mother and his wife, he was so disturbed by the bad teaching and poor example of church leaders that he became bitter toward the things of God.
Indeed, it is a privilege to be an elder, a deacon, a Sunday school teacher, or a Bible club leader. But it is also an awesome responsibility. Let's make sure we attract people to the Savior rather than turn them away.
