"While we were yet unloving and unlovely in character, “hateful, and hating one another,” our heavenly Father had mercy on us. “After that the kindness and love of God our Saviour toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us.” Titus 3:3-5 . His love received, will make us, in like manner, kind and tender, not merely toward those who please us, but to the most faulty and erring and sinful. MB 75.1"
"For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another. But after that the kindness and love of God our Saviour toward man appeared, Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;"
Ellen White directly references Titus 3:3-5 in this passage.
