Grow in the grace and knowledge of our Lord.
—2 Peter 3:18
When you reached your grown-up physical height—somewhere between age 15 and 20—you were as tall as you would ever be.
But spiritual growth continues for a lifetime. Or should.
When Peter concluded his second letter, “Grow in the grace and knowledge of our Lord and Savior Jesus Christ,” he was ending the letter as he began it: he had opened it telling disciples to “Make every effort” to grow—specifying eight qualities to cultivate (2 Pt 1:5–7).
When we became disciples, we enrolled in the School of Christ for a lifetime. No commencement ceremony is scheduled: no one is awarded a diploma from the School of Christ during their lifetime.
From the day of our new birth until the day of our death, we are to grow in the grace and knowledge of our Lord.
The Christian life is like riding a bicycle
—unless you keep moving, you fall.
