The blessings of a Bible study can be seen in the changes for good that it makes in people’s lives. (Heb. 4:12) For example, a woman, after only three studies in the Truth book, became aware that God is to be worshiped “with spirit and truth.” (John 4:23, 24) She noted particularly such Scripture texts as “guard yourselves from idols” and “flee from idolatry.” (1 John 5:21; 1 Cor. 10:14) The very next week she removed the religious pictures from her walls, pictures that she and her family had idolized for years. Why did she do this? Her reply: “Only God is to be worshiped.”​—Matt. 4:10.

A Catholic woman who was very active in church affairs went to her priest and asked him about the use of God’s name. “He acknowledged God’s name to be Jehovah,” she said, “but he felt it was not necessary to use it. What about images and medals? He said they were all superstitions. He encouraged me to read the Bible, as he said, ‘there is power in it. If it puts the love of Jesus Christ in your heart to become one of Jehovah’s witnesses, then you must do it.’ Two weeks later I dropped completely out of the Roman Catholic Church when I realized I couldn’t worship in a hypocritical way.”

A Sunday-school teacher, after a few studies in the Truth book, went to her minister and informed him of her desire to become one of Jehovah’s witnesses. She resigned as the Sunday-school teacher and asked that her name be removed from the church membership rolls. Her husband also had his name removed.

A drug addict tells about living communally with six other addicts when a minister of Jehovah’s witnesses began to study the Bible with him. “What a wonderful change it made in our lives!” he says. “The so-called drug-induced ‘spiritual experiences’ look hollow when compared to any hour of our present lives. Now eight months have passed and my wife and I are eagerly approaching baptism, and are participating in the Theocratic Ministry School and the field ministry.”

A minister writes about a young woman he had met in the door-to-door ministry and with whom he began studying the Truth book: “The very first study was just amazing! It was very evident this person was going to make rapid spiritual progress! On the second study we covered two chapters. By the time the third study was conducted she was attending all the Thursday and Sunday meetings. This was the truth, she knew it and she wanted it.”
