Perhaps it was not the intent of the question, but I see the question as it relates to whole story of mankind as described in scripture and in accord with God has shown me. The simple answer is that God did intervene. He sent His Son:
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." John 3:16
People are too often expecting favor here and now in this world of evil men for their own personal situation. God, of course, has already handled all that needed to be handled... leaving the rest to whom other than the person who must choose his own ways or God's Way.
The details of the here and now [our fleshly "course" or period of time] are meaningful as they relate to the whole picture, and who but God can see the whole picture? Our brother
@Christ4Ever cited in particular Isaiah 55:8-9 which is the whole situation for unbelievers and in the measure that their vision is still through a "glass darkly" for believers. Without vision [the "eyes to see" of which see speaks] what happens to people?
"Where there is no vision, the people perish..." Prov 29:18
"And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind." John 9:39
"For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known." I Cor 13:12
This "course" [our allotted time as a person of flesh] is important, but it is ultimately only a preliminary to the final result for those who make it to the end on His side, isn't it?
