"We who believe the truth should be very careful to give no occasion for our good to be evil spoken of. We should know that every step we take is in accordance with the Bible; for those who hate the commandments of God will triumph over our missteps and faults, as the wicked did in 1843. EW 70.1"
"Let not then your good be evil spoken of:"
The EGW passage directly echoes the sentiment of Romans 14:16, urging believers to avoid giving occasion for their good to be spoken of as evil. The connection is clear and intentional.
"May 14, 1851, I saw the beauty and loveliness of Jesus. As I beheld His glory, the thought did not occur to me that I should ever be separated from His presence. I saw a light coming from the glory that encircled the Father, and as it approached near to me, my body trembled and shook like a leaf. I thought that if it should come near me I would be struck out of existence, but the light passed me. Then could I have some sense of the great and terrible God with whom we have to do. I saw then what faint views some have of the holiness of God, and how much they take His holy and reverend name in vain, without realizing that it is God, the great and terrible God, of whom they are speaking. While praying, many use careless and irreverent expressions, which grieve the tender Spirit of the Lord and cause their petitions to be shut out of heaven. EW 70.2"
"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 describe an encounter with the divine that results in a profound sense of unworthiness and awareness of God's holiness. Isaiah's reaction to seeing the Lord is mirrored in EGW's description of her body trembling and shaking in the presence of God's glory.
