“But grow in the grace and knowledge of our Lord and Savior Jesus Christ.” – 2 Peter 3:18

Growth always happens “in grace”.

The truest measure of our growth is not our behavior, it’s our grasp of grace–a grasp which involves coming to deeper and deeper terms with the unconditionality of God’s love.

It’s also growth in “the knowledge of our Lord and Savior Jesus Christ.” This doesn’t simply mean learning facts about Jesus. It means growing in our love for Christ because of what he has already earned and secured for us and then living in a more vital awareness of that grace.

Our main problem in the Christian life is not that we don’t try hard enough to be good, but that we haven’t believed the gospel and received its finished reality into all parts of our life.
