Emphasizing that the vast majority of people who claim to be Christians are actually lost, deceived, false Christians, and will end up in Hell. The true Christians are only few. This is the same kind of teaching the Lord Jesus Christ emphasized in Matt. 7:13-14, 21-23. True Christians have been completely and obviously changed by the Holy Spirit whereby they receive entirely new affections and desires for God, holiness, righteousness, and purity. False Christians, on the other hand, merely profess Jesus as Lord and profess to be saved and yet they’ve never been changed and they still love their sins and wicked practices.
