Recently I was blessed by 2 different sermons by 2 different individuals. They were both on dealing with special needs and how God uses suffering for good in our lives. Truly, I can't even begin to repeat them. Please take some time to hear them for yourself, especially if you are enduring some type of hardship in your life.

You will be blessed and refreshed as I was!
