2 Corinthians 4:16-18

So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.

"The Bible teaches about different kinds of suffering. There is suffering because of sin (David and Bathsheba). There is suffering because of someone else’s sin (Achan). There is suffering for the sake of righteousness (Paul). There is suffering when the cause is not immediately discernible (Job). Paul’s words here apply most directly to the latter two kinds of suffering. The only way to consider real and deep affliction as light is to see them compared to the weight of eternal glory. As you go through hardships in your life, seek God’s grace to suffer well and to have an eternal perspective, focusing on those things that are not seen and are eternal."
