What the Bible says about Christ Never Deviates from His Character
(From Forerunner Commentary)
We need only to grasp Paul's overall point here. Jesus Christ, our Example and Savior, will never deviate from His character; He "is the same yesterday, today, and forever" (Hebrews 13:8). The apostle gives this admonition directly to God's children: Despite how we may personally relate to God as shown by how we live, our Savior will always be faithful to God and His purpose. He will live and act as He truly is regardless of what we personally think or how we live our lives. This is what we, too, must strive to do.
Thus, two applications to our lives follow: God loves and mercifully and generously gives to His children, but He also judges, requiring His children to live up to standards that glorify Him and His Family.
