“Peter’s commitment to Jesus isn’t sustained by Peter. Peter remains committed to Jesus because Jesus is steadily committed to Peter. Just before Peter denies his Lord, Jesus promises to never let him go: “I have prayed for you that your faith may not fail” (Luke 22:32). If it weren’t for grace, Peter would be finished.
The same is true for you. Your Bible-reading plan, prayer life, and baptized New Year’s resolutions are not what tether God’s heart to you. It’s because of Jesus—and it will always, forever be because of Jesus—that God loves you. If it weren’t for grace, we’d all be done for, because there’s a little bit of Peter in every one of us. We are all prone to wander. Not only does Jesus not abandon Peter, but He uses him as a major catalyst in establishing His kingdom on earth. Jesus doesn’t just put up with Peter—He delights in Peter despite his offensive behavior and never, ever stops pursuing Peter with His grace.”
