When you believe in Jesus Christ, you become "born of the spirit", which means that you receive the gift of the Holy Spirit. It is critical for one to know if he has the Holy Spirit or not. Paul made clear that to be born of the spirit one must resign one's self to the cross, be moved towards repentance, and a change will take place. People wanted to be good, right, etc. but they din't know the Holy Spirit. Pastor Troy explains how only the Holy Spirit living in you can these things be possible.
