Jesus dealt with this in Matthew 16, let’s take a look what this means and how it applies to eschatology.
The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven. He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.A wicked and adulterous generation looks for a sign, but none will be given it except the sign of Jonah.” Jesus then left them and went away. Matthew 16:1-4
The Pharisees were hounding Jesus for more miracles to prove who He was. Just like many Christians today, who are so focused on fads and new teachings, they totally ignore Who and What Christ is. Even though Jesus gave them miracles that were greater than even Moses had shown, their faith was absent and their focus was skewed.
The leaders were so concerned with appearances and their made-up doctrine they could not, nor wanted to see the real Truth. Sound familiar? They interpreted and applied their ideas and judgments from the Law, but did not understand God’s plain truth as revealed in the Scriptures. So, they focused on trivial matters and burdened the people with silly laws that were not scriptural. Just like false teachers do today! They became obstacles to the truth and facilitators of confusion. They literally believed, with passion, the weather report based on superstitions, but not God’s Word based on fact! They could see the sky and predict tomorrow’s errands, but were unwilling to see God at work or His plan.
A sign from heavenhea. Literally means, point to the sky and show us! This did not refer to a sign from God; Jesus already gave them that. This was an astrological proclamation. Often the leaders would use astrologers and star predictions for understanding the signs of the times and the future, even though God did directly forbid it (2 Kings 20:8-9; 2 Chron. 32:24; Isa. 38:7).
They relied on superstitions and not spiritual maturity. Superstitions were rooted in Jewish custom; Josephus wrote that the heavens, as shown to men, had a special portion to predict future events (Judges 6:17; Isa. 7:11-14; 8:18; 19:20; 20:3; 37:30; 38:7; 66:19; Ezek. 4:3; 12:11; 24:24-27; Matt. 24:29).
Elijah countered the astrologers by making a sign on the spot (1 Kings 18:38).
They were looking for proof from fables, and refused to see the real proof as predicted by the prophets. Thus, it can be said the leaders were looking for a sign from God, but that is unlikely due to the fact that Jesus already gave them many.
The best sign in eschatology is the buildup of our faith and the deployment of our spiritual formation into the lives of others. We pave the way for His Second Coming by our faith development and deployment, not by our feeble theories and the chasing of signs!
Their problem was not the lack of signs, but the refusal to adhere to them. God had given them the signs, but they refused to read or obey them (Duet. 32:5-20). The ultimate sign would be the resurrection (Matt. 12: 39-40).
We need to understand our Lord’s worth; He is Worthy, He sees us as worthy to be saved. We need to see that worthy means honorable and precious, so we need to empty ourselves of pride and concerns so as to be worthy to worship Him. The this becomes the beacon sign to the unbeliever.
