The efficacy of the gospel in Word and Sacrament has nothing to do with the will, works, or faith of man but is established according to the command and institution of God (Is. 55:11). Through the gospel in Word and Sacrament, God offers salvation to all believers (Romans 10:8-9; Mark 16:16; Luke 22:19, 20). Natural man can and will resist and reject the salvation offered through the gospel(1 Cor. 2:14).

Specifically, with respect to the efficacy of baptism to the one without faith, so what if some do not believe? "Shall their unbelief make the faith of God without effect?" Romans 3:3.
