who killed both the Lord Jesus and their own prophets, and drove us out, and didn't please God, and are contrary to all men;
And they please not God - Their conduct is not such as to please God, but such as to expose them to his wrath; 1 Thessalonians 2:16. The meaning is not that they did not aim to please God - whatever may have been the truth about that - but that they had shown by all their history that their conduct could not meet with the divine approbation. They made extraordinary pretensions to being the special people of God, and it was important for the apostle to show that their conduct demonstrated that they had no such claims. Their opposition to the Thessalonians, therefore, was no proof that God was opposed to them, and they should not allow themselves to be troubled by such opposition. It was rather proof that they were the friends of God - since those who now persecuted them had been engaged in persecuting the most holy people that had lived.
