Saying the sinner's prayer with faith in your heart can only make you a believer or a baby in the faith (teknon), not a disciple of Jesus Christ. Sometimes, it's hard to differentiate between teknons and sinners. Through discipleship, teknons are groomed to become mature disciples or sons (huios). Only huios can drive and advance God's kingdom on earth. The Great Commission is summarized thus:

1. Preach to sinners to get converted and become teknons.

2. Train (disciple) teknons to become huios.
