For those who are led by the Spirit of God are the children of God. The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, “Abba, Father.” The Spirit himself testifies with our spirit that we are God’s children. Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his suffering sin order that we may also share in his glory.
Romans 8:14-17
Every person in the world is loved by God. Every human being is created in God’s image. Because of this, some people think this means that every person is a child of God. We’ve heard people say, “We are all God’s children.” Yet, that isn’t what we read over and over again in scripture.
Every person is invited into the family of God, but not everyone has accepted that invitation. Scripture is clear. We aren’t children of God from birth. We become children of God through faith in Jesus Christ. When we receive the Holy Spirit, the Spirit testifies with our spirit that we are God’s children. Those who are led by the Spirit are children of God.
So while everyone is loved by God, not every person is a child of God. It takes faith in Jesus to be adopted into the family of God. Paul said it this way to the Galatians:
So in Christ Jesus you are all children of God through faith, for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
Galatians 3:26-29
There are some key phrases in that passage. “In Christ Jesus” we are children of God “through faith.” And, “if you belong to Christ” then you are an heir in the family of God. These are important qualifiers. We must belong to Christ, through faith, in order to be considered a child of God. John says something similar in his Gospel:
Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God—children born not of natural descent, nor of human decision or a husband’s will, but born of God.
John 1:12-13
According to John’s Gospel, the right to become children of God is a special right. It is not automatic. It is something we become. And the ones who have been given the right to become children of God, born of God, are the ones “who did receive him” and “believed in his hame,” that is, Jesus. The message is clear. We must receive Jesus into our life and believe in Him in order to become children of God.
See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is.
1 John 3:1-2
Notice that there is a separation between “the world” and the “children of God.” The world has a hard time with children of God because it had a hard time with Jesus. This distinction would make no sense if everyone in the world was automatically a child of God. Yes, everyone is loved by God. Yes, everyone has been created in God’s image. But no, not everyone is a child of God, not until they give their life to Jesus and receive the Holy Spirit.
The old platitude that “we are all God’s children” may sound nice, but it’s just not true. All are invited into the family of God, but not all have accepted the invitation. We are not automatically children of God. We become children, adopted into the family, through faith in Jesus. Through that faith in His name we receive the Holy Spirit, who is our sign and seal that we are in the family of God.
And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance…
Ephesians 1:13-14
