In 1944 Criswell was called to replace George Washington Truett as the pastor of the First Baptist Church in Dallas. He would spend the remainder of his life at First Baptist, preaching more than four thousand sermons from its pulpit. During his tenure membership grew from 7,800 to 26,000, with weekly Sunday School attendance in excess of 5,000. The church expanded to multiple buildings covering five blocks in downtown Dallas, eventually becoming the largest Southern Baptist church in the world. The popular evangelist Billy Graham joined the church in 1953, became a close friend of the Criswell family, and remained a member of the Dallas congregation for 55 years.
