By saying that He will even hand us over to burning for the sake of sufferings, torment and all sorts of ills
Notes from Wikiquote
the same is true if we say that He acts or thinks with spite | and with a vengeful purpose, as though He was avenging Himself. | Among all His actions there is none which is not entirely a matter of mercy, love and compassion | this constitutes the beginning and the end of His dealings with us. | 39.22, p. 172
