It was interesting for me to note the effect Isaiah had on the discipleship of King Hezekiah. More interesting to note the response he had to the spiritual influence of Isaiah almost to the point where they were sincerely one. It looks to me that Hezekiah had an earnest desire, as a devout disciple, to match Isaiah’s insistent attitude of quietness and confidence – that is, a steadfast trust in God alone. That trust in Him meant there were no conversations about aligning Israel with any foreign powers.
What I loved most about Hezekiah was as his internal spiritual strength grew, so did his insight and vision about tomorrow. He quietly prepared for emergencies. He ruled with a mild and just administration which voided any revolt from those he served as king and he took measures to fortify and build up the defense of the capital.
He set to work resolutely and built up all the wall that was broken down and raised towers upon it,[a] and outside it he built another wall, and he strengthened the Millo in the city of David. He also made weapons and shields in abundance. – 2 Chronicles 32:5 ESV
He did this long before the Assyrian crisis was imminent. He could not learn his lesson of faith all at once. Through all the gossip, possible rebellion, and Assyria, he weathered them because Isaiah walked with him. A great model for discipleship.
