True believers and true followers of Christ are people who have experienced a new birth. Note that there are many people who claim to be Christians. Perhaps they have Christian parents, or received a Christian education, or were born in a supposedly Christian nation, or accept Christianity as a good religion. They might even be attending a church, or trying to do good works, or agreeing with Christian beliefs intellectually.
However, none of those things can make someone a true follower of Christ. Only those people who experience the new birth become true followers of Christ. The evidence of the new birth is the presence of the Holy Spirit within, confirming a person to be God’s child.
The Holy Spirit in you will help you to realize that God knows you personally and you are so special to Him.
