"When all that we have and are is not consecrated to God, selfish interests close our eyes to the importance of the work, and the means that God calls for is withheld. But He who has lent us this means for the advancement of His cause will frequently withdraw His prospering hand and in some way scatter the means thus withheld, and it will be lost to its possessor and lost to the cause of God. It is not preserved in this world or in the world to come. God is robbed, and Satan triumphs. The Lord would have you closely search your own heart, Brother O, and get the love of the world out of it. Die to self, and live unto God. Then will you be of that number who are the light of the world. 2T 690.2"
"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 concept of robbing God by withholding what is due to Him. Malachi 3:8 specifically mentions tithes and offerings, while EGW speaks more generally about withholding means for the advancement of God's cause. The connection is thematic, focusing on the idea of depriving God of what is rightfully His.
"For where your treasure is, there will your heart be also."
The EGW passage discusses the importance of consecrating all to God and not being selfish, which directly relates to the principle in Matthew 6:21 about where your treasure is, there your heart will be also. The EGW passage expands on the consequences of not following this principle.
"I have been shown that you were cherishing erroneous views in regard to the future, views savoring of the pernicious sentiments of the Age-to-come. You sometimes talk out these ideas to others. But they are not in harmony with the body. You do not make a right application of Scripture. When Jesus rises up in the most holy place, and lays off His mediatorial garments, and clothes Himself with the garments of vengeance in place of the priestly attire, the work for sinners will be done. The period of time will then have come when the mandate will go forth: “He that is unjust, let him be unjust still: ... and he that is righteous, let him be righteous still: and he that is holy, let him be holy still. And, behold, I come quickly; and My reward is with Me, to give every man according as his work shall be.” 2T 690.3"
"He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still."
The EGW passage directly quotes Revelation 22:11, making it an explicit allusion.
