"But evil men and seducers shall wax worse and worse, deceiving, and being deceived."
Such phrases as, "day by day," carry with them the thought of routine. But "worse and worse," of degree. The former stays pretty much the same, the latter progressively moves downward. Examples: the woman with the issue of blood, "...was nothing bettered, but rather grew worse"; and the man out of whom went an unclean spirit and upon returning, "...taketh to him seven other spirits more wicked than himself...and the last state of that man is worse than the first."
Don't allow some politician or religious leader, whether they be sincere or a charlatan, lead you astray in this matter. Prior to the First World War, many believed the world was getting better. Since then, their breed has noticeably thinned out; though, like always, there are a few dyed-in-the-wool hangers-on. Most certainly, there have been times of, call them what you will, revival, refreshing, renewal, awakening. But none have lasted. Like every dispensation, age, or time period in the Bible, all ended in apostasy.
To say Christians are going to bring in an age of righteousness through the power of the Holy Spirit, in my humble opinion, is sheer nonsense. The props for that theory were knocked down at Pentecost. If ever a Utopian age was to be brought in without the personal, physical presence of Christ, it was then. To say the world is going to get so good it will usher in the return of Christ, is like me saying I am going to get so good, God will save me.
I realize this article will not be accepted or received by some, any more than Jeremiah's message to the people of his day, when he told them, things were going to get worse before they got better.
