Almost as silly as Saul of Tarsus, arch-persecutor of Christians being chosen not only as an Apostle, but as the most effective and influential Apostle.
haha
Yes - and that isn't even what I was talking about.
But, that is another illustration. Saul/Paul was certainly met with... lack of confidence by people who thought they understood God's will.
Could it be, that non-believers are also Children of God? Or is it only some select ones? If that's true, how are we to know which God has selected and which He hasn't? Did not Jesus say (Matthew 25:31-46) to treat "the least" as if they were Jesus Himself? This includes strangers - people who we don't even know their religious background. To me, this says that God's love extends beyond the Believers.
I know there is a split of authority on this, but "strangers" is specifically referenced. Particularly when He changes up the formulation when describing the accursed. For the blessed, they fed/clothed/quenched "my brothers." For the accursed, they failed to feed/clothe/quench the least "of these" - of those who were hungry/oppressed/thirsty. The implication of family is removed. That seems important.
