"It was not at first perceived that if the decree did not go forth at the beginning of the year 457 B. C., the 2300 years would not be completed at the close of 1843. But it was ascertained that the decree was given near the close of the year 457 B. C., and therefore the prophetic period must reach to the fall of the year 1844. Therefore the vision of time did not tarry, though it had seemed to do so. We learned to rest upon the language of the prophet: “The vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry.” Habakkuk 2:3 . LS 58.1"
"For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry."
EGW directly quotes Habakkuk 2:3 and applies it to the perceived delay in the fulfillment of the prophecy.
"God tested and proved His people by the passing of the time in 1843. The mistake made in reckoning the prophetic periods was not at once discovered, even by learned men who opposed the views of those who were looking for Christ's coming. Scholars declared that Mr. Miller was right in his calculation of the time, though they disputed him in regard to the event that would crown that period. But they, and the waiting people of God, were in a common error on the question of time. LS 58.2"
"And thou shalt remember all the way which the Lord thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no."
Both passages discuss God testing and proving His people through a period of waiting and difficulty. Deuteronomy 8:2 refers to the Israelites' wilderness experience, while the EGW passage refers to the disappointment of 1844.
"Those who had been disappointed were not long left in darkness; for in searching the prophetic periods with earnest prayer the error was discovered, and the tracing of the prophetic pencil down through the tarrying time. In the joyful expectation of the coming of Christ, the apparent tarrying of the vision had not been taken into account, and was a sad and unlooked-for surprise. Yet this very trial was necessary to develop and strengthen the sincere believers in the truth. LS 58.3"
"Knowing this, that the trying of your faith worketh patience."
Both passages highlight the idea that trials and disappointments can strengthen faith. James 1:3 speaks generally about the testing of faith, while the EGW passage applies this principle to the specific experience of the Millerites.
