"In answer to his petition, Daniel received not only the light and truth which he and his people most needed, but a view of the great events of the future, even to the advent of the world's Redeemer. Those who claim to be sanctified, while they have no desire to search the Scriptures or to wrestle with God in prayer for a clearer understanding of Bible truth, know not what true sanctification is. SL 48.2"
"At the beginning of thy supplications the commandment came forth, and I am come to shew thee; for thou art greatly beloved: therefore understand the matter, and consider the vision."
The EGW passage directly references Daniel receiving light and truth in answer to his petition, which is explicitly described in Daniel 9:23. The reference to understanding the vision is also a clear connection.
