"And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ."
This verse describes the apostles' continuous proclamation of Jesus Christ, which parallels the idea of going forth and proclaiming the Sabbath more fully.
"This view was given in 1847 when there were but very few of the Advent brethren observing the Sabbath, and of these but few supposed that its observance was of sufficient importance to draw a line between the people of God and unbelievers. Now the fulfillment of that view is beginning to be seen. “The commencement of that time of trouble,” here mentioned does not refer to the time when the plagues shall begin to be poured out, but to a short period just before they are poured out, while Christ is in the sanctuary. At that time, while the work of salvation is closing, trouble will be coming on the earth, and the nations will be angry, yet held in check so as not to prevent the work of the third angel. At that time the “latter rain,” or refreshing from the presence of the Lord, will come, to give power to the loud voice of the third angel, and prepare the saints to stand in the period when the seven last plagues shall be poured out. EW 85.3"
"And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book."
The passage speaks of a 'time of trouble' before the plagues, which aligns with Daniel 12:1's description of a time of trouble such as never was before the deliverance of God's people.
