Hezekiah was took the threat from Assyria before the Lord in prayer by publicly laying the king's letter before him in the temple. He continued to pray both publicly and privately throughout his life. We can follow Hezekiah's example by making prayer a central part of our return to God.
Revival starts in your heart with just the decision to fully follow God even if it means going against what those around you and those who have gone before you are doing. The fire you light in your heart can quickly light fires in the people and communities you connect with and become a movement of transformation.
