This gives man too much control over his salvation. Salvation is by grace, then it is an internal work of the Holy Spirit. Telling someone to “make a decision for Christ” and to “express” that decision outwardly fosters the notion that salvation is synonymous with walking an aisle or reciting a prayer instead of being the work of the Holy Spirit (John 3:8). This false association, in turn, can lead to false conversions, because someone who walks an aisle after a sermon may think he is saved (on the basis of an emotional experience), when there has been no work of God in his heart. Nowhere in the Bible are “decisions for Christ” mentioned, nor is anyone commanded to “accept Christ” or to “ask Him into your heart.”
Those who are saved are saved by grace through faith. Even faith is a gift created through the hearing of God’s Word (Romans 10:17). Salvation does not come by walking an aisle or raising a hand. Saying a prayer does not save anyone. Salvation is making a new spiritual creation, something only the Holy Spirit can accomplish.
Coming to the front of a church is not the same thing as coming to Christ. Simply “making a decision” of some kind is not what saves us; it is the all-powerful, sovereign work of God in Christ that saves. Rather than calling on people to “invite Jesus to come in,” it would be better to urge them to repent of their sin and cast themselves on the mercy of God in Christ.
