C.W. Slemming draws out the spiritual lessons to be learned from the study of the worship rituals of Israel by focusing on the five Levitical offerings, the principle of the Sabbath, and the seven feasts of the Lord. From these he shows what God desires of His worshipers in these New Testament days.
C.W. Slemming was converted in 1919 and served for 11 years in the pastorate, but realized that the Lord had graciously given him the gift of Bible teaching. In 1946 he left local church ministry to join the staff of Bible Testimony Fellowship, which involved traveling throughout Britain conducting weeks of Bible studies. He was later appointed director of BTF. In 1949 he made the first seven visits to the USA for a Bible teaching tour. During this period he charted every book of the Bible and wrote a commentary entitled The Bible Digest, receiving a doctorate of divinity for his work. In 1974 he was called home to glory.
Slemming teaches the modern believer what God desires in worship through the study of worship rituals of Israel from the Old Testament.
