Because many spiritual leaders (and their church members) have a weak understanding about progressive sanctification, the process of sanctification often becomes nothing more to them than a list of moral directives or some vague notion concerning doing good works. For this reason, a clear distinction must be made between the indwelling and infilling Holy Spirit. The above reason also is why a clear distinction must be made between the work of the Holy Spirit in justification and the work of the Holy Spirit in progressive sanctification. Furthermore, if these distinctions are not taught, then the spiritual leaders with their weak understanding about progressive sanctification will no doubt be responsible for creating the last days’ lukewarm Laodicean Christians (cf. Revelation 3:14-22)!
