"***** At the day of judgment there comes to the lost a full realization of the meaning of the sacrifice made on Calvary. They see what they have lost by refusing to be loyal. They think of the high, pure association it was their privilege to gain. But it is too late. The last call has been made. The wail is heard: “The harvest is past, the summer is ended, and we are not saved.” Jeremiah 8:20 . 7T 16.1"
"The harvest is past, the summer is ended, and we are not saved."
Ellen White directly references Jeremiah 8:20 in this passage.
"object of Christ's supreme regard. He is making experiments of grace on human hearts and is effecting such transformations of character that angels are amazed and express their joy in songs of praise. They rejoice to think that sinful, erring human beings can be so transformed. 7T 16.4"
"Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth."
Both passages highlight the joy of angels over the repentance and transformation of sinners. Luke 15:10 specifically mentions the joy in the presence of the angels of God over one sinner who repents. The EGW passage speaks of angels being amazed and expressing their joy in songs of praise at the transformation of human character through Christ's grace.
