True conversion not only has two sides; it also impacts a person on three levels—intellect, emotion, and will. In order to experience true conversion, a person must know something, feel something, and do something.
1. Know. In order to be converted, a person must know of his lost condition (Rom 3:20; Ps 51:3–4; Ezek 36:31) and know that Jesus is the divine remedy for sin (Rom 10:13, 17; Ps 109:10; Phil 3:8). True conversion is a result of knowing and believing the basic facts of the gospel—the death, burial, and resurrection of Jesus for our sins.
2. Feel. In order to be converted, a person must have a broken and contrite heart over his sin (Jer 31:19; Ps 51:17; 2 Cor 7:10f) and feel drawn to Christ (John 6:44, 65; 1 Thess 2:13). True conversion is a result of feeling the guilt and shame for one’s sin.
3. Act. In order to be converted, a person must also turn from his sin (Acts 26:18; Ezek 14:6; 2 Cor 7:11) and turn to Christ in reliance on him alone for salvation (Acts 15:11; 16:31; Phil 3:9). This faith is expressed by calling on the Lord to save you (Rom 10:9,13), this repentance in changing the way you live.
Many of the people who respond to an invitation, pray a prayer, and fill out a card have never experienced true conversion. The gospel has penetrated their intellect and even their emotions but not their will. Faith does not become saving faith until it impacts all three.
James wrote that even demons have a faith that impacts their intellect (they know there is one God) and emotions (they shudder), but it does not save them because it does not result in a change in their behavior.
