They know that they could not be redeemed apart from the grace of God or the work of Jesus Christ, but they assume that the reason they believed, while their friends persisted in unbelief, was that they made the right decision and their friends made the wrong decision. Such Christians assume that somehow they, not God, were the decisive factor.
This seems to equate faith with works, when faith is by grace, as seen in Eph 2:8,9.
