St. Maximos the Confessor: Perfect love does not split up the single human nature...

Perfect love does not split up the single human nature, common to all, according to the diverse characteristics of individuals; but, fixing attention always on this single nature, it loves all men equally. 

It loves the good as friends and the bad as enemies, helping them, exercising forbearance, patiently accepting whatever they do, not taking the evil into account at all but even suffering on their behalf if the opportunity offers, so that, if possible, they too become friends. If it cannot achieve this, it does not change its own attitude; it continues to show the fruits of love to all men alike. 

It was on account of this that our Lord and God Jesus Christ, showing His love for us, suffered for the whole of mankind and gave to all men an equal hope of resurrection, although each man determines his own fitness for glory or punishment.
