"The Sin That Will Keep Many Church Members Out of Heaven" gives some often overlooked insights into the sin Jesus said in Matthew at the end of the Sermon on the Mount will keep many praying church members and great church workers out of heaven. This sin is the core sin for which Jesus died and is very often overlooked or lightly regarded as just another sin or seen simply as gross sin. This sin drives every other sin that can be found in man. It is the mother and father of all sins and often, according to Jesus, remains in the lives of many who have united with the church and are very active in the works and ministries of the church. This sin is very subtle and is the most devastating sin of all because it can be very easily overlooked. William A.
