"Chapter 43—A Higher Experience We need constantly a fresh revelation of Christ, a daily experience that harmonizes with His teachings. High and holy attainments are within our reach. Continual progress in knowledge and virtue is God's purpose for us. His law is the echo of His own voice, giving to all the invitation, “Come up higher. Be holy, holier still.” Every day we may advance in perfection of Christian character. MH 503"
"But as he which hath called you is holy, so be ye holy in all manner of conversation;"
Both passages emphasize the call to holiness. EGW's 'Come up higher. Be holy, holier still' echoes the sentiment in 1 Peter 1:15, though it's not a direct quote.
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord."
Both passages discuss spiritual growth and striving for a higher, holier experience. The EGW quote's invitation to "Come up higher. Be holy, holier still" echoes the idea of being transformed "from glory to glory".
"Those who are engaged in service for the Master need an experience much higher, deeper, broader, than many have yet thought of having. Many who are already members of God's great family know little of what it means to behold His glory and to be changed from glory to glory. Many have a twilight perception of Christ's excellence, and their hearts thrill with joy. They long for a fuller, deeper sense of the Saviour's love. Let these cherish every desire of the soul after God. The Holy Spirit works with those who will be worked, molds those who will be molded, fashions those who will be fashioned. Give yourselves the culture of spiritual thoughts and holy communings. You have seen but the first rays of the early dawn of His glory. As you follow on to know the Lord, you will know that “the path of the righteous is as the light of dawn, that shineth more and more unto the perfect day.” Proverbs 4:18 , R.V., margin. MH 503.2"
"But the path of the just is as the shining light, that shineth more and more unto the perfect day."
Ellen White directly references Proverbs 4:18 in this passage.
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord."
The EGW passage directly references the concept of being "changed from glory to glory," which is a clear allusion to 2 Corinthians 3:18. The context of spiritual transformation and beholding God's glory further strengthens the connection.
"And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God."
Both passages address the desire for a deeper understanding and experience of God's love and fullness. While not a direct quote, the longing for a "fuller, deeper sense of the Saviour's love" in EGW parallels the desire "to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God".
