I know the title seems like a very odd statement.  How can suffering lead to comfort? Suffering is a bad thing in the eyes of man, something we would choose to avoid at all costs, we would rather do without our entire lives.  Unfortunately it is not possible for us to go without suffering.  All of us have and will experience suffering to some degree in our lives, and some of us are experiencing it at this very moment.  But the idea that it can lead to comfort might seem like a rather bold statement until we look at what Paul says in 2 Corinthians 1.

"Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God."  (2 Cor. 1:3-4 )

God comforts us in all our troubles.  So in our troubles we receive comfort.  In addition to that we can receive comfort from others who have received that same comfort in their troubles.  Once we have received comfort in our troubles from God, we are to be sharing that comfort with others.  So available to us in our troubles is comfort from two sources.  God, the God of comfort, and others who have known this comfort.  The passage goes on to say "For just as the sufferings of Christ flow over into our lives, so also through Christ our comfort overflows." (2 Cor 1:5 )

When we suffer we recieve comfort in the same measure through Chirst.  God is a God of comfort.  He wants to comfort us in all our troubles.  He is able to do so because He has compassion that is immeasurable.  We have seen this demonstrated when He sent Christ, and we can recieve the comfort we need when we open our hearts fully to Him. Go to God in prayer, allow Him to give you your comfort in your time of trouble.
