One of my child hood friends became a pharmacy professor. Another one got an MD and PhD from 2 Ivy League schools. Another one became a doctor. Another one also became a doctor. Another one became a top computer science CEO in Silicon Valley.
What all these people had in common was that they believed in God and built deep emotional connections with their friends. Over half of them would cry when I left their homes or we got into arguments as young children and all of them disclosed their true self to me and were willing to be vulnerable around the people they trusted.
A person who never believes anybody, never trusts anybody and is never willing to let somebody impress them or amaze them or humble them, lives alone. They do not give anybody emotional space in their lives. All my successful Christian friends were willing to be vulnerable around those they loved because Jesus was vulnerable around those He loved. They did not depend on others for validation but they were willing to care about others, even if it meant personal heart break for them.
