why are we comforted?

ever hear people preach about how God will comfort you in a time of need? and have you every wondered why? over my time in churches i hear preachers preach of God comfort in our times of need, and they always leave it at that. the idea is, if you are hurt, God will comfort that hurt - and all that is cool, but again, why? why does God comfort us? well, paul shares some insite into that when he writes to the church in corinth:
He comes alongside us when we go through hard times, and before you know it, he brings us alongside someone else who is going through hard times so that we can be there for that person just as God was there for us.
so, the "why" is so that we can comfort others who have the same pains. the idea is that we are to help others and help them find comfort. we are to give as we recieve - as God gives to us we are to give to others.
