“You are to be perfect, just as your Father is perfect” (Matt. 5:48) seems like an impossible goal until we understand the meaning of the word translated as “perfect.” Luke’s parallel — “be merciful” (Luke 6:36) — helps us understand perfect and shows us a deep meaning under the Festival of (Re)Dedication of the Temple, or Chanukah. To be mature believers, to be righteous, we must dedicate all of ourselves — devotion and weakness — to God.
Yeshua pointed to the actions He was doing through His Father’s power as evidence that He and the Father were “one,” that His “temple” — His body — was whole dedicated to God’s purpose (John 10:22–30). Our “temples” should be wholly dedicated to God as well.
