"The Bible has its kernel, its life, its center, which is constituted with the church, Christ, the Spirit, and life. These four items are the contents of the true substance of the Bible. The revelation of the Bible, particularly the New Testament, stresses these four matters: the church, Christ, the Spirit, and life. If we remove these four items from the New Testament, all that remains would merely be dead letters. These four crucial elements are also the four important items in the Lord’s recovery today. Hence, we must all have a deep impression, a fresh light, and a renewed understanding concerning these four crucial elements."
