“Be perfect, just as your Father in heaven is perfect” (Matthew 5:48).
“Be perfect.” Jesus didn’t say that because you’re not allowed to make mistakes. “Perfect” (teleios) means to become complete, whole, and filled with God’s character. Any time you do fail, it’s an opportunity to grow closer to God by letting him transform your thinking to become even more like him.
“Be perfect” isn’t God’s religious standard of behavior. It’s an invitation to experience the depths of his grace.
