Sister, the angel told us through her that we will understand more in the future. He even told us what we will learn after learning "what even is", sunset. We will learn "when it is", that it takes place in the middle of the first day and not at the beginning. I know God helped our church understand the longest time to make this correction by holding an incorrect hour for more than 8 years before doing the Bible study to learn more. God prepared our church to understand His Sabbath. Note that the angel speaks positively that we will "understand, but not yet, not yet". It is difficult to correct a tradition, especially one that has been around for so long! We understood "what even is" but we have not understood "when it is": even falls in the middle of the first day and not as supposed was at the beginning because the Sabbath in Israel is not as supposed a day of the week.
I saw that it is even so: “From even unto even, shall ye celebrate your Sabbath.” Said the angel: “Take the word of God, read it, understand, and ye cannot err. Read carefully, and ye shall there find what even is, and when it is.” I asked the angel if the frown of God had been upon His people for commencing the Sabbath as they had. I was directed back to the first rise of the Sabbath, and followed the people of God up to this time, but did not see that the Lord was displeased, or frowned upon them. I inquired why it had been thus, that at this late day we must change the time of commencing the Sabbath. Said the angel: “Ye shall understand, but not yet, not yet.” Said the angel: “If light come, and that light is set aside or rejected, then comes condemnation and the frown of God; but before the light comes, there is no sin, for there is no light for them to reject.” I saw that it was in the minds of some that the Lord had shown that the Sabbath commenced at six o'clock, when I had only seen that it commenced at “even,” and it was inferred that even was at six. I saw that the servants of God must draw together, press together. (Testimonies for the Church, vol. 1, Page 116)
United in our hope for the soon return of Jesus, Jorge
