Advice needed

A few weeks ago, I wrote about an experience I had in church of hearing a voice. The voice told me not to forget about Gerrell's friend Neal. Gerrell was concerned that Neal didn't know Jesus. So...on the advice of one of the pastor's at my church, I wrote Neal a letter. Here is a part of what the letter said:

"So...I am convinced that the voice that spoke to me in church was telling me I needed to move forward with Gerrell's desire. I have to admit I am not very experienced with talking to those who don't know Jesus. All I can do is share what is in my heart. The basis of having a relationship with Jesus is believing that He died on the cross for the forgiveness of my sins and in that, I have the hope of salvation. In return for that great gift, we are to live our lives in a way that would be pleasing to God--serving him in every way we can. I believe that all believers will, when we leave this earth, live forever with Jesus in heaven. I truly believe that is where Gerrell is now. Part of his concern for those he loved that didn't know Jesus was that he wasn't going to see those people in heaven."

I ended the letter with this:
"The purpose of this letter was not to try and force you into anything. Instead I wanted you to know Gerrell's desire for you and that I am here to help in whatever way I can. I will continue to pray for you that your heart will be stirred."

I haven't heard anything from Neal. It has been about 2 weeks since I mailed the letter. I am not sure what to do next. Neal is not a close friend of mine--I grew to know him through Gerrell. I am struggling with what to do now. Should I follow up with him? I don't want him to feel like I am pressuring him at all. Should I do nothing? Any suggestions would be greatly appreciated.
