The moment he entered the pulpit, Wigglesworth would say, “All those who want something from God, put up your hand.” Hands would go up all over. Then he would say, “All those who are going to be blessed, put the other hand up.” Nearly everybody would put up their other hand and have both hands in the air. Next he would say, “Keep those hands raised; and if you are going to take the blessing with you when you go home, stand up.” Obeying, almost everyone would stand with both hands still raised. Waves of glory would then sweep the congregation. The atmosphere was always electric. A multitude of needs were met during those times.
