See what great love the Father has given us: We’re even called children of God! And that’s what we really are. The world doesn’t know us, because it didn’t know him.
Those who do live under the control of their wrong desires think about what sin wants. But those who live under the control of the Spirit think about what the Spirit wants.
If the Spirit of God truly does live in you, you’re not ruled by your desires—you’re ruled by the Spirit. Anyone who doesn’t have the Spirit of Christ doesn’t belong to Christ.
In other words, God’s children aren’t all those who are physically descended from Abraham. Rather, they’re the children God promised to him. Those are the ones who are considered to be Abraham’s children.
The one who obeys God’s commands lives in him, and he lives in them. Here’s how we know that God lives in us: We know it by the Holy Spirit he gave us.
