In the Bible, the Hebrew word tam or tamim, translated as “perfect” doesn’t mean what we think it means.
When Jesus says in the Sermon on the Mount (Matthew 5:48) “Be therefore perfect, even as your Heavenly Father is perfect,” He is not commanding us to be as flawless as God. The Hebrew word for “perfect” here means to be complete, mature, or healthy.
Similarly, the Greek word, telos, speaks of perfection as being fully ripened. Think of a piece of ripe fruit that has a slight bruise on one side. Both Greeks and Hebrews of Jesus’ day would describe the fruit as being “perfect” because something can be mature and still have flaws.
With this in mind, read Jesus’ words again:
“Be therefore complete, even as your Heavenly Father is complete.”
“Be therefore mature (fully ripe), even as your Heavenly Father is mature.”
“Be therefore healthy, even as your Heavenly Father is healthy.”
The bottom line is: you can be complete, mature, and healthy without being perfect as the English means it, and it is God’s desire that you are!
