Although Lee attended Southern Baptist services and Sunday school in his youth, he was never converted nor baptized by them.

After her conversion, Lee's second sister began to pray for him and introduced him to a Chinese pastor who encouraged him to attend his Sunday morning services.

Inspired by the preaching of Peace Wang, Lee dedicated himself to serve God for the rest of his life in April 1925 at the age of 19.

During this time, Lee began to feel that God was calling him to quit his job and serve as a full-time minister, which he did in August 1933.

Soon afterward, he received a letter from Watchman Nee that read, “Brother Witness, as for your future, I feel that you should serve the Lord with your full time.

He also traveled to the northwestern provinces of Suiyuan, Shanxi, and Shaanxi to preach the gospel and edify Christians there prior to the Japanese invasion in 1937.

At the end of 1942 a revival broke out in Yantai, and the church met continuously for one hundred days.

Under suspicion of espionage due to his experimentation with evangelism by migration, Lee was arrested by the Imperial Japanese Army in May 1943 and underwent a month's interrogation through flogging and water torture.

Nee charged Lee to instruct, teach, and lead the elders and to make arrangements concerning the church services, as well as the purchase of land for the building of a new meeting place.

Nee then returned to mainland China where, in 1952, he was imprisoned for the remaining twenty years of his life by the CCP.

Lee believed that by practicing the God-ordained way, churches could be saved from oldness and degradation and be brought back to a biblical pattern.

[16] The God-ordained way consists of four major steps:[17] The first step of the God-ordained way is to fulfill the New Testament priesthood of the gospel to seek, visit, and contact sinners for God's salvation to make the sinners organic members of the Body of Christ and offer them to God as the New Testament sacrifice (Rom.

The second step is to nourish and cherish the newborn babes in Christ in home meetings as nursing mothers (1 Thes.

The third step is to perfect the saints by mutual teaching in group meetings for the work of the ministry to build up the organic Body of Christ (Eph.

14:1–5, 23–26, 31, 39a).In February 1994 Lee began to deliver messages on subjects he referred to as "the high peak of the divine revelation."

[1] Witness Lee was critical of Christendom as a system while stressing the need to accept all believers based on what he taught was the common faith (Tit.

A radio broadcast called Life-study of the Bible with Witness Lee was later produced from these spoken messages.

[20] Following the Life-study Lee began a focused Crystallization-study to look at high points, or "crystals," of each book of the Bible.
