Paul has been making the point that those who are of faith in Christ are sons of God and therefore heirs of God’s promises also (Gal. 3:26-29). In 4:1-11, Paul shows us that every single one of us, no matter our background, was in slavery prior to meeting Christ. We were all held in slavery to something. Jews were enslaved to God’s law. Gentiles didn’t have God’s law, but were enslaved nevertheless to cultural, national, and tribal ideas, values, philosophies, prejudices, power imbalances, etc. And yes, even we enlightened North American, western thinkers were and are enslaved too! Behind the scenes, evil spiritual beings are manipulating and twisting things to such an extent that we are enslaved under them. How do we come out from under this slavery? Most of us don’t even know we are slaves. We think we are free human beings determining our own fate.
We have a God who is always pursuing us to release us from our slavery and make us his sons and heirs! If he hadn’t moved through his Son and in his Spirit we would still be slaves. Let’s worship him for who he is and for all he has and is still doing to rescue us!
