Galatians 4 says the heir is “lord of all,” yet lives under tutors until the Father’s time. The point isn’t ownership—it’s alignment. The Patēr (Source) intends that what’s in the Bottle (the Father) is what’s in the glass (sons and daughters). Through the Lord’s Prayer we learn the posture—Your kingdom come, Your will be done—and in John 17 we’re sent as Jesus was, sanctified in truth so the world sees the Father in us. With the great cloud of witnesses, we lay aside every weight and run (Heb. 12:1), because the Spirit bears witness that we are heirs and joint-heirs with Christ (Rom. 8:17).
This is maturity: not just carrying a title, but carrying the content—His mind, His love, His holiness, His power. When people “taste” our lives, they should recognize the same life that is in the Father and the Son. If you’ve seen the glass, you’ve seen the Bottle. Now, grow into what you’ve been born to inherit.
