"The life that Christ lived in this world, men and women can live through His power and under His instruction. In their conflict with Satan they may have all the help that He had. They may be more than conquerors through Him who loved them and gave Himself for them. 9T 22.1"
"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
Both passages emphasize living a life empowered by Christ and His sacrifice. EGW speaks of living the Christ life through His power, while Galatians 2:20 describes Christ living in the believer and the life being lived by faith in Him.
"The lives of professing Christians who do not live the Christ life are a mockery to religion. Everyone whose name is registered on the church roll is under obligation to represent Christ by revealing the inward adorning of a meek and quiet spirit. They are to be His witnesses, making known the advantages of walking and working as Christ has given them example. The truth for this time is to appear in its power in the lives of those who believe it, and is to be imparted to the world. Believers are to represent in their lives its power to sanctify and ennoble. 9T 22.2"
"But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price."
The EGW passage directly references and expands upon the concept of a 'meek and quiet spirit' as an 'inward adorning,' which is a clear allusion to 1 Peter 3:4.
"Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
Both passages discuss the importance of Christians living lives that reflect their faith and serve as a witness to others. EGW emphasizes representing Christ and revealing a meek spirit, while Matthew 5:14-16 uses the metaphor of light to illustrate the same principle.
