Heirs With Christ
To be united with Christ means to be indwelled by his Spirit. Every power we have, every new desire we have, is given to us by the Holy Spirit. To be united with Christ is a core function of the Spirit. He is the one who connects us to the vine, who fills us with new life, who carries us forward to the day of Christ. Because we are united to him by his Spirit, we then are adopted children, given the inheritance of the Son of God and all that accompanies it.
