It will never be the religious leaders who bring national revival.
What happened when Christ came? Some wise men came and inquired about the birth of the Christ. Never once does the scripture suggest that any of the religious leaders investigated what the wise men said. Later when Christ was teaching the religious leaders were only concerned about their position.
John 11:48 If we let him thus alone, all men will believe on him: and the Romans shall come and take away both our place and nation.
Later when the Apostles were preaching it was much the same.
Acts 4:21 So when they had further threatened them, they let them go, finding nothing how they might punish them, because of the people: for all men glorified God for that which was done.
The miracles performed by Christ and His Apostles only concerned them because it might affect their position of leadership and the status quo.
This is also the why behind new information being introduced to most “Christian” churches today is rejected. It destroys the status quo and usually ends up with the preacher losing his income, half the congregation leaving or both.
The best example we have in scripture of a religious revival besides Christ was with King Hezekiah. Read the version of the story in 2 Chronicles 28 – 30. No, he wasn’t perfect. Recently we’ve had a president that disturbed the status quo. He isn’t perfect either as his ties to those who are anti-Christ is strong. He did put money toward religious freedom and removed money from evil. Much of that has now been undone.
Remember it is God who saves. God does use men, but it is still only God who saves.
