1. Because of our status as adopted children of God, the Father has sent the Spirit into our hearts (vv. 4-6).
2. The Holy Spirit is identified as the Spirit of God’s Son (v. 6).
3. The Holy Spirit enables us to commune intimately with God as a loving heavenly Father (v. 6).
Getting God’s Fatherhood right matters more than it might seem, this sermon argues, insisting God the Father is a person, not an impersonal force behind the universe. Believers follow after Christ’s own Sonship, not a generic religious concept of divine parentage. Being children of God, on these terms, is a specific, personal relationship, not a metaphor for cosmic belonging.
