We establish from Scripture that believers can and should enjoy an assurance of their salvation - indeed, they are commanded to make their calling and election sure. This understanding runs counter to the teaching of certain churches down through the years.
We also see that it is possible for unbelievers to have a counterfeit assurance and we consider the Pharisees in the New Testament as one example of such people. We see the nature of counterfeit assurance and of genuine assurance. All are urged to come to a true and growing assurance of salvation.
