"If all were devoted to God, a precious light would shine forth from them, which would have a direct influence upon all who are brought in contact with them. But all need a work done for them. Some are far from God, variable and unstable as water; they have no idea of sacrifice. When they desire any special indulgence or pleasure, or any article of dress, they do not consider whether or not they can do without the article, or deny themselves the pleasure, and make a freewill offering to God. How many have considered that they were required to make some sacrifice? Although it may be of less value than that of the wealthy man who possesses his thousands, yet that which really costs self-denial would be a precious sacrifice, an offering to God. It would be a sweet-smelling savor, and come up from his altar like sweet incense. 2T 127.1"
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
Both passages connect shining light with good works and influence on others. EGW elaborates on the idea of sacrifice and devotion as a source of this light.
"Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings."
Both passages address the idea of offering to God. Malachi focuses on tithes and offerings, while EGW speaks more broadly about sacrifice and self-denial. The connection is present, but not as strong as other pairs.
"The youth are not authorized to do just as they please with their means, regardless of the requirements of God. With David they should say: “Neither will I offer burnt offerings unto the Lord my God of that which doth cost me nothing.” Quite an amount of means has been expended to multiply copies of their pictures. Could all enumerate the amount given to the artist for this purpose, it would swell to quite a large sum. And this is merely one way in which means is squandered, invested for self-gratification, from which no profit is received. By this outlay, they are not clothed or fed, the widow and the fatherless are not relieved, the hungry are not fed, the naked are not clothed. 2T 127.2"
"And the king said unto Araunah, Nay; but I will surely buy it of thee at a price: neither will I offer burnt offerings unto the Lord my God of that which doth cost me nothing. So David bought the threshingfloor and the oxen for fifty shekels of silver."
EGW directly quotes 2 Samuel 24:24, making it an explicit allusion. The context of sacrifice and cost is also relevant in both passages.
