A dear friend recently asked me, ‘What’s the scriptural basis for calling all people “God’s people”?’ This is a major sticking point for many, based on the scriptures in the New Testament that seem to indicate that only believers in Christ are children of God.
It’s a great question for which I don’t have a direct answer. I’ll have to see if I can find any “proof texts” that says such (LOL)! Seriously, though, there are several different biblical themes that contribute to my belief in this so this might be a little dense and complicated (In my head, it’s a lot simpler)! To try and help with this, I’ll do a small series of posts that addresses this question.
