"I saw that some professed Sabbathkeepers spend hours that are worse than thrown away, in studying this or that fashion to decorate the poor, mortal body. While you make yourselves appear like the world, and as beautiful as you can, remember that the same body may in a few days be food for worms. And while you adorn it to your taste, to please the eye, you are dying spiritually. God hates your vain, wicked pride, and He looks upon you as a whited sepulcher, full of corruption and uncleanness within. 1T 134.1"
"Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men’s bones, and of all uncleanness."
EGW directly uses the phrase "whited sepulcher" and applies it to those who are outwardly beautiful but inwardly corrupt, mirroring the condemnation in Matthew 23:27. This is a clear and direct allusion.
"Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;"
Both passages address the issue of outward adornment versus inward spirituality. While 1 Peter 3:3 specifically mentions jewelry and hairstyles, EGW broadens the scope to include general fashion and decoration of the body. The core message of prioritizing inner beauty over outward appearance connects them strongly.
Mothers set the example of pride for their children, and, by so doing, sow seed that will spring up and bear fruit. The harvest will be plenteous and sure. That which they sow, they shall reap. There will be no failure in the crop. I saw, parents, that it is easier for you to teach your children a lesson of pride, than a lesson of humility. Satan and his angels stand right by your side to make the act of yours, or the word that you speak to them, effectual to encourage them to dress, and in their pride to mingle with society that is not holy. O parents, you plant in your own bosoms a thorn that you will often feel in anguish. When you would counteract the sad lesson you have taught your children, you will find it a hard thing. It is impossible for you to do this. You may deny them things that would gratify their pride, yet it still lives in the heart, longing to be satisfied; and nothing can kill this pride but the quick and powerful Spirit of God. When this finds its way to the heart,…
"Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap."
EGW directly quotes and applies the principle of "whatsoever a man soweth, that shall he also reap" from Galatians 6:7 to the context of parents teaching pride to their children. This is a clear and direct application of the biblical principle.
"may meekly, yet decidedly, give a reason of their hope. This reason of their hope, I saw, they must have to strengthen their own souls for the fierce conflict. Without this they are wanting, and cannot have firmness and decision. 1T 134.3"
"But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:"
The phrase 'reason of their hope' is a direct quote from 1 Peter 3:15, making this an explicit allusion.
