Understanding that discipleship begins with evangelism but involves more, the question remains as to how Christians are shaped as disciples. Certainly much of what is involved with such Christian sanctification is coming to know more truth. Without a proper set of beliefs, one will not behave in a manner worthy of Christ.
An important question every Christian must ask is, What does it mean to be a disciple of Christ? Very simply, a disciple will observe all that Christ commanded. In other words, a disciple of Jesus Christ will be characterized by certain behaviors. Christians are a new people of God (1 Peter 2:9) whose behavior should emerge from and reflect their biblical beliefs and values. This is why Scripture gives such attention to the behavior of Christians; it should be holy as God is holy (1 Peter 1:15–16). Although Christians are new creatures (2 Cor 5:17) with new hearts of obedience to Christ (Rom 6:17–18), holy behavior is not something that comes automatically. Observing Christ’s commands, as the Great Commission explicitly states, is something that must be taught. In other words, true conversion is not simply assent to certain facts; it is a life-changing entrance into communion with God. It is “turn[ing] to God from idols to serve a living and true God” (1 Thess 1:9–10).
