What does the Bible say about being perfect?

In Matthew 5:48, Jesus instructs us to 'be ye therefore perfect, even as your Father, which is in heaven is perfect.' This command underscores the standard of perfection required by God, aligning with Genesis 17:1 where God tells Abraham to 'be thou perfect.' The concept of perfection in Scripture relates to being complete, without blemish, and in accord with divine truth. It's important to understand that believers are seen as perfect in Christ Jesus, as through Him, we are justified and sanctified, meeting God's requirement of perfection.
