What happens when we obey God

So yesterday at church there was a guy who many people in the church had been praying for and he came to my church and gave his life back to Christ. When he came in I could smell the smell of beer and cigarrettes on him when he sat right behind me. I then felt God saying to me to talk to him after church. I was wondering what God wanted me to say but he told me not to worry and he would provide words to say. So as I was talking with him I found out that he had grown up in the church and then walked away from God for awhile. As we got to talking God was having me share my story with him. He mentioned that he was terrified of girls (as well as many other things that we talked about) but to make a long story short he felt calm after I talked with him. He said he felt peace when I talked with him. This is a guy in his early 30's. Thanks God for giving me this opportunity to share you with someone else.
