Jesus said this in Matthew 5:48: “Your heavenly Father is perfect.” So what does it mean to be perfect? For something to be perfect requires two things. It must possess every quality that is desirable and excellent, and it must lack everything that would be considered a flaw or undesirable. For example, a perfect diamond would have every single quality that makes a diamond great, and it couldn’t have any flaws or any undesirable qualities. To say that God is perfect means that he possesses only excellent qualities and there’s no desirable quality that God doesn’t have. You and I can’t be perfect in this lifetime but we can strive to be more like God each day.
