"For His anger endureth but for a moment; in his favor is life: weeping may endure for a night, but joy cometh in the morning."
I believe this verse emphasizes brevity. It is written in both a pattern and words that emphasizes this with one exception. That exception lies in the phrase, "favor is life." This means that His favor to those that are His is for a lifetime - forever. His chastisement is over quickly, our grief only for a night, but after this - there is joy for eternity.
Look at the verse in light of your present circumstance. Perhaps you have had sin struggles and have been chastised or have asked for forgiveness from Him. That anger of His at your sin was only momentary in comparison to the love He has for you. The weeping and grief you now experience over perhaps your sin, unfulfilled expectations, or loss is also only momentary in light of the joy that you will have forever "in the morning" when He comes and relieves of you of your earthly weight.
II Corinthians 4:16-17 reminds us of this as well - specifically verse 17, "For our light affliction, which is just for a moment, worketh for us a far more exceeding and eternal weight of glory."
