We can easily get caught in the evangelical trap that our words must be convincing, our actions conveying. Don't get me wrong, these things do have an importance but, perhaps not in the ways we would think matter. The Lord will surely use our words and actions in conjunction with everything else He has implemented to incline hearts unto Himself. We are told in the NT "where He is lifted up, He will draw others unto Himself".
For those that insist that Jesus never claimed to be God, that He never suggested a Triune godhead, that He had not existed before His human birth, or that He had become enlightened by some secret knowledge or presence, this verse requires a whole lot of re-explaining. For those of us who accept Him at His word it just flows as written.
It is interesting here that especially with Israel that God would be using the self same source of Judah's sin (Israel's false religion) as the subjecting hammer over Judah. It should be clear to Judah how God feels about their idolatry.
Is this a common occurance? Is the kings life extended because he asked for it? or was it extended because in this time and place against Assyria Hezekiah's life meant more to God's plan than starting over with a new king in Judah? If so, then why did God allow his health to deteriorate in the first place? To affect the kings judgements from here on out?
