For God does not show favouritism. Romans 2:11
For the Lord your God is God of gods and Lord of lords, the great, mighty and awesome God, showing no partiality and accepting no bribe. Deuteronomy 10:17
Then Peter began to speak: “I now realize how true it is that God does not show favoritism, but accepts from every nation the one who fears him and does what is right.” Acts 10:34
As for those who were held in high esteem – whatever they were makes no difference to me; God does not show favoritism – they added nothing to my message. Galatians 2:56
Since you call on a Father who judges each person’s work impartially, live out your time as foreigners here in reverent fear. 1 Peter 1:17
One principle that is repeated throughout the Bible is the idea that God does not show partiality, does not show favouritism. He doesn’t play favourites. If someone doesn’t obey his commandments, he will punish them no matter who they are. After all, God commands us not to show favouritism. It makes sense that he would perfectly instantiate this principle himself. Calvinism teaches that certain individuals are chosen by God for salvation and others are “passed over” and are therefore destined to become damned. God does this irrespective of anything in the lives of those people, their belief in him, their fear of him or their obedience to him. If that is true, then it means that God does play favourites. What does it mean to say that God does not show favouritism? It doesn’t mean that God behaves exactly the same way to everybody. It means that he does not apply standards to some that he does not apply to others. He doesn’t give some people a chance that he does not give to others. The passage in Deuteronomy quoted above puts this vividly by saying that God does not accept bribes. Accepting bribes is wrong because it results in uneven scales. The standards being applied to some people are different from the standards being applied to others.
The Calvinist doctrine of election implies that God does show partiality, because he gives mercy to some that he does not give to others; he applies standards to some that he does not apply to others; he gives some people a chance that he does not give to others.
