Tozer writes in “The Knowledge of the Holy“:
Divine goodness, as one of God’s attributes, is self-caused, infinite, perfect, and eternal. Since God is immutable He never varies in the intensity of His loving-kindness. He has never been kinder than He now is, nor will He ever be less kind. He is no respecter of persons but makes His sun to shine on the evil as well as on the good, and sends His rain on the just and on the unjust. The cause of His goodness is in Himself; the recipients of His goodness are all His beneficiaries without merit and without recompense.
The whole outlook of mankind might be changed if we could all believe that we dwell under a friendly sky and that the God of heaven, though exalted in power and majesty, is eager to be friends with us.
But sin has made us timid and self-conscious, as well it might. Years of rebellion against God have bred in us a fear that cannot be overcome in a day. The captured rebel does not enter willingly the presence of the king he has so long fought unsuccessfully to overthrow. But if he is truly penitent he may come, trusting only in the loving-kindness of his Lord, and the past will not be held against him.
Meister Eckhart encourages us to remember that, when we return to God, even if our sins were as great in number as all mankind’s put together, still God would not count them against us, but would have as much confidence in us as if we had never sinned.
