Our hope in Christ
Therefore we do not lose heart. Even though our outward man is perishing, yet the inward man is being renewed day by day.
For our light affliction, which is but for a moment, is working for us a far more exceeding and eternal weight of glory, while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal.
2 Corinthians 4:16-18
Fanny Crosby, the blind hymn writer who wrote Blessed Assurrance, Jesus is mine and more than a thousand other hymns, knew this truth well. She said,
"It seemed intended by the blessed providence of God that I should be blind all my life, and I thank him for the dispensation. If perfect earthly sight were offered me tomorrow I would not accept it. I might not have sung hymns to the praise of God if I had been distracted by the beautiful and interesting things about me."
