How Calvinists Should Engage in Controversy

Some really good advice from John Newton: How Calvinists Should Engage in Controversy – Justin Taylor:

But if you look upon him as an unconverted person, in a state of enmity against God and his grace, (a supposition which, without good evidence, you should be very unwilling to admit,) he is a more proper object of your compassion than your anger. Alas! “he knows not what he does.” But you know who has made you to differ. If God, in his sovereign good pleasure, had so appointed, you might have been as he is now; and he, instead of you, might have been set for the defence of the Gospel. You were both equally blind by nature. If you attend to this, you will not reproach or hate him, because the Lord has been pleased to open your eyes, and not his.
