Paul wrote that the gospel is God’s power unto salvation (Rom. 1:16). Many people in modern religions deny this. It is obvious the Jew, Muslim, Hindu, and Buddhist reject the gospel altogether. However, it just as true that denominations do not believe the gospel is the power unto salvation. There may be exceptions, but they are very few.
Some believe the gospel is totally unnecessary to salvation. Their belief is that the Holy Spirit works directly on the heart of a sinner. In some mysterious way the Spirit is supposed to awaken a person to his or her sin and bring them to faith in the Lord. Each person has a different and unique experience that confirms the Spirit’s work. In other words, it is all subjective and based on feelings and emotions.
