Question: How do you help someone that won't talk, other than prayer?

The best thing that anyone can do for someone who does not initially open up (which is the case with most people) is to befriend them. This may seem like a simple act, but I assure you that this is not always an easy task. In each case that Jesus talked with someone He was able to connect with them in a personal way. He knew who they were and where they came from and what was important to them. This was the same in Paul's ministry to those he went to; he was always in a place for an extended amount of time. The thing that is most important is to be the example in each and everything you do, making sure it glorifies God. Take the time to get to know the people you want to help. Hang out with them, do things they are interested in as long as it does not compromise your faith and God. The reward will be great you will gain a friend and you may find out you were the one blessed. God relationship with us is a personal relationship and so should the relationships we make. I once read a story in a book about a person who was ministering (helping) to people and one of the people asked him with much concern; "If I never become a Christian will you still be my friend") We are called by God to lead people to the Most High God, we do not abandon those who do not understand our ways, we continue to be a light for them.
