Shalom.
I believe that you are saying that to make the world a better place starts with the individual and having a personal relationship with Christ. That those who have the Holy Spirit know that they do.
Shalom.

Correct , but an individuals contribution to making the world a better place is "faith" or the application of Faith pisteuo or faithing. What is that contribution? "A personal surrender to Him , and a life inspired by such surrender."
But nobody comes to Christ unless the Father draws them . So making the world a better place doesn't accually start with the individual , it starts with God the Father , the one who makes it possible for us to recieve His Sons Spirit.
