In Life-study of James, Witness Lee emphasizes two key points related to the Epistle of James—first, that the believers must progress in practical Christian perfection, and second, that the believers must be careful not to cultivate such perfection without a clear vision concerning the law and grace of God in God’s New Testament economy. In Life-study of First Peter, he describes the Christian life under the government of God with its high demand, and in Life-study of Second Peter, he details the divine provision that supplies the believers with all that they need to meet that high demand.
