Hezekiah brought Israel back to worship of the One True God. Isaiah shows us that worship isn't just about sining songs in the temple but doing the whole work of God in everything we do and everywhere we go.
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.
