"***** The world will never know the work secretly going on between the soul and God, nor the inward bitterness of spirit, the self-loathing, and the constant efforts to control self; but many of the world will be able to appreciate the result of these efforts. GW 323.1"
"But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly."
Both passages emphasize the importance of private, secret communion with God. The EGW passage highlights the internal struggles and self-control involved in this process, while Matthew 6:6 focuses on the reward for praying in secret.
"***** Those who have the deepest experience in the things of God, are the farthest removed from pride or self- exaltation. It is when men have the most exalted conceptions of the glory and excellence of Christ, that self is abased, and they feel that the lowest place in His service is too honorable for them. GW 323.2"
"Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts."
Both passages deal with the humbling effect of encountering God's holiness and glory. Isaiah's reaction to seeing the Lord is one of deep unworthiness, which aligns with EGW's statement that those with the deepest experience of God feel the lowest place is too honorable.
"***** The Lord wants us to come up into the mount, more directly into His presence. We are coming to a crisis which, more than any previous time since the world began, will demand the entire consecration of every one who has named the name of Christ. GW 323.3"
"And the Lord said unto Moses, Come up to me into the mount, and be there: and I will give thee tables of stone, and a law, and commandments which I have written; that thou mayest teach them."
Both passages involve a call to ascend to God's presence on a mountain. While Exodus 24:12 is a literal call to Moses, EGW uses it metaphorically to represent a deeper spiritual connection with God, especially in times of crisis.
