Peter denied Jesus, to preserve himself physically (Mark 14:66-72). Later he denied the gospel, to preserve himself socially (Galatians 2:11-21). But by the time he wrote his first letter, his heart had been set free: “I have written briefly to you, exhorting and declaring that this is the true grace of God. Stand firm in it” (1 Peter 5:12).
What is “the true grace of God”? Not survival, physical or social, but the privilege of sharing in Christ’s sufferings that we may also rejoice when his glory is revealed (1 Peter 4:13). Whatever life thrusts upon us, the true grace of God is to stand firm in that hard place and embrace identification with Jesus.
