"***** Dear Reader, A sense of duty to my brethren and sisters and a desire that the blood of souls might not be found on my garments have governed me in writing this little work. I am aware of the unbelief that exists in the minds of the multitude relative to visions, also that many who profess to be looking for Christ and teach that we are in the “last days” call them all of Satan. I expect much opposition from such, and had I not felt that the Lord required it of me, I should not have made my views thus public, as they will probably call forth the hatred and derision of some. But I fear God more than man. EW 76.1"
"Wherefore I take you to record this day, that I am pure from the blood of all men."
EGW's statement about not wanting the blood of souls on her garments directly echoes Paul's declaration in Acts 20:26, where he states he is 'pure from the blood of all men'. Both express a sense of responsibility for sharing truth and warning others.
"When the Lord first gave me messages to deliver to His people, it was hard for me to declare them, and I often softened them down and made them as mild as possible for fear of grieving some. It was a great trial to declare the messages as the Lord gave them to me. I did not realize that I was so unfaithful and did not see the sin and danger of such a course until in vision I was taken into the presence of Jesus. He looked upon me with a frown and turned His face from me. It is not possible to describe the terror and agony I then felt. I fell upon my face before Him, but had no power to utter a word. Oh, how I longed to be covered and hid from that dreadful frown! Then could I realize, in some degree, what the feeling of the lost will be when they cry, “Mountains and rocks, fall on us, and hide us from the face of Him that sitteth on the throne, and from the wrath of the Lamb.” EW 76.2"
"For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ."
Both passages deal with the idea of pleasing God versus pleasing men. EGW's passage describes her struggle to deliver messages faithfully, even when it meant risking disapproval. Galatians 1:10 directly addresses the same conflict. The reference to Revelation is also valid, but the primary connection is to Galatians.
Presently an angel bade me rise, and the sight that met my eyes can hardly be described. A company was presented before me whose hair and garments were torn and whose countenances were the very picture of despair and horror. They came close to me and took their garments and rubbed them on mine. I looked upon my garments and saw that they were stained with blood, and that blood was eating holes in them. Again I fell like one dead at the feet of my accompanying angel. I could not plead one excuse. My tongue refused all utterance, and I longed to be away from such a holy place. Again the angel stood me upon my feet and said, “This is not your case now, but this scene has passed before you to let you know what your situation must be if you neglect to declare to others what the Lord has revealed to you. But if you are faithful to the end, you shall eat of the tree of life and shall drink of the river of the water of life. You will have to suffer much, but the grace of God is sufficient.” I …
"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 involve a prophet feeling unworthy and unclean in the presence of God/an angel. Isaiah's confession of unclean lips mirrors EGW's inability to plead an excuse and her desire to be away from the holy place. The imagery of uncleanness and unworthiness connects them.
