Book excerpt: Thinning hair, failing eyesight, and arthritic hands reveal an inescapable truth: we're only getting older. But that doesn't mean we should simply sit back and take it easy. In Finishing Our Course with Joy, renowned theologian and author J. I. Packer challenges us to embrace old age as an opportunity for continued learning, careful planning, and heartfelt discipleship. Packer's pastoral words and personal stories encourage us to press on toward the upward call of God with endurance and grace—that we might continue to glorify God in our aging and finish our lives with joy.
