The idea of quality of life is overrated.
We wouldn’t consider Paul or Jesus to have had “quality of life”.
Timothy had physically ailments 1 Tim 5:23.
Yet they lived out God’s calling with impactful lives.
My fear of aging is suffering and “quality of life” for myself and/or my husband. If my husband is paralyzed by a stroke, both of us will suffer. I don’t want to suffer. I’ve gone through some suffering and lived through it. I can see God’s faithfulness through all of it. The pain has dimmed over time. But prior suffering hasn’t made me braver to face future suffering.
God reminds me that He will never leave me nor forsake me. No matter how the world defines “quality of life”, my life WITH CHRIST IS quality of life.
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. 2 Cor 4:17-18
Be of good cheer, I have overcome the world.
