We may face many things in our Christian walk. Our path is not always strewn with roses. I believe that when God helps us through some trial or problem, we should indeed help someone else who may be going through the same situation. Many times we have gone through some trial and God ministered to us in a wonderful way. We shouldn't keep that ourselves. We should share it because we never know who it might help.
Many times Christians go through something and Satan has them convinced that they are the only ones that this has happened to and that there is no way out. Then God sends someone along who has faced the same thing, and oh the difference it makes to know that you're not alone.
1 Cor 10:13 says that there is no temptation that hasn't been faced by someone else. It also says that God is faithful and will not allow it to overcome you, but will make a way of escape for you. So, if God has helped you in any way, unless it is too personal, share it. You'll never know who you'll help.
