In 2 Corinthians 4:16-18 Paul goes on, “Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.
This is perhaps the best news of all related to our suffering in this life, and a cause for us to be encouraged in the midst of trouble. Though our bodies are being battered and crushed, and our souls are being stretched and tormented, the results for our eternal selves are wonderful. We are being strengthened. We are gaining in eternal glory and honor. We are attaining eternal benefits for our temporary pressure.
This means we need to focus on the presently invisible but enduring blessings which are accrue to us through the temporary adversities we face. Delayed gratification is essential to the life of a disciple. It is necessary for our survival and is a defining characteristic of a follower of Christ.
