Doubt: Faith amid the Silence of God

Alright men. I really want your input on this one, I'll try and keep it short. We all know that faith is hard. As Christians we are to practice 'solidarity' with the world, showing them the riches of faith in Christ. But also, we are to be apart - because we do live in the liberation of Christ. But the difficulty that I mention here is a different kind.

I ask, have you ever doubted. Not in God's ability, or your ability, or in faith. No, have you ever doubted in such severity that you feel that you can no longer call yourself a Christian? Have you ever been so burned out with faith, that for a time...you loose it. This doubt comes differently to all non-infants of faith. For some, the pain hits when they proclaim the new life of Christ, and yet...there is not even a spark to light it within themselves. For others, it is when they wake up one day to feel as though they have the understanding that their faith holds no ground, and they search for the foundation that holds their foundation. For yet others, it is simply when they come to the cold realization that they stand in a night, alone with nothing but silence. They cannot feel, hear, or see God any longer - eventually being stripped of their ability to commune with him. and yet, so often than not, these three examples seem to coincide with each other - a person who has experienced one, experiences the others. It is a topic that I have searched deeply into, as (I do not claim to be an expert) I am no stranger to bumpy roads in faith myself. But before I explore those possibilities with you all, I am curious - to those who have suffered or are suffering a profound difficulty in believing. What did you find? God Bless.
