Childbirth is a great example of pain that ends in joy. We will have times in our lives where there will be sorrow and weeping, but God promises that He will turn those times into dancing because of the goodness that will come from it. We are not promised an exemption from the pains and suffering of this world, but we are promised hope within which we can grieve during those times. The hope comes only from Christ who redeems all things.
