"The imagination must be positively and persistently controlled if the passions and affections are made subject to reason, conscience, and character. You are in danger, for you are just upon the point of sacrificing your eternal interests at the altar of passion. Passion is obtaining positive control of your entire being—passion of what quality? of a base, destructive nature. By yielding to it, you will embitter the lives of your parents, bring sadness and shame to your sisters, sacrifice your own character, and forfeit heaven and a glorious immortal life. Are you ready to do this? I appeal to you to stop where you are. Advance not another step in your headstrong, wanton course; for before you are misery and death. Unless you exercise self-control in regard to your passions and affections, you will surely bring yourself into disrepute with all around you, and will bring upon your character disgrace which will last while you live. 2T 562.1"
"Keep thy heart with all diligence; for out of it are the issues of life."
The EGW passage directly reflects the principle in Proverbs 4:23, emphasizing the importance of guarding one's heart (mind, affections) because it determines the course of one's life. The call to control the imagination and passions aligns with the need to diligently keep the heart.
"You are disobedient to your parents, pert, unthankful, and unholy. These miserable traits are the fruits of a corrupt tree. You are forward. You love the boys, and love to make them the theme of your conversation. “Out of the abundance of the heart the mouth speaketh.” Habits have become powerful to control you; and you have learned to deceive in order to carry out your purposes and accomplish your desires. 2T 562.2"
"O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh."
EGW directly quotes Matthew 12:34.
I do not consider your case hopeless; if I did, my pen would not be tracing these lines. In the strength of God you can redeem the past. Your name is already a byword in -----; but you can change this by using the powers which God has given you. You may even now gain a moral excellence so that your name may be associated with things pure and holy. You can be elevated. God has provided for you the necessary helps. He has invited you to come to Him, and has promised to bear your burdens and give you rest of soul. “Learn of Me,” says the divine Teacher, “for I am meek and lowly in heart: and ye shall find rest unto your souls.” You have long been above this lowliness and meekness. You will have to learn this important lesson of the divine Teacher before you can find the rest promised. You have thought so much of yourself, of your own smartness, that it has led you to such affectation and vanity as to make you almost a fool. You have a deceitful tongue, which has indulged in misrepresentat…
"Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls."
EGW directly quotes Matthew 11:29.
"Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool."
Both passages discuss the possibility of redemption and transformation despite past sins. While not a direct quote, the theme of changing one's life and being forgiven is present in both.
