Obedience!

He trusted in the LORD God of Israel, so that after him was none like him among all the kings of Judah, nor who were before him.
That was Hezekiah, Why would the Bible say such a thing about this man?
For he held fast to the LORD; he did not depart from following Him, but kept His commandments, which the LORD had commanded Moses. 2 Kings 18:6
"Him," means the LORD in that passage.
So why was he spoken of greatly? Because he obeyed the commands of the LORD! Now we all know that is important because the Bible speaks well of the man who does obey! And the bible does not only speak well of him but it says that no other king was ever like him!
Now consider the Pharisees, people thought they obeyed the commands of the LORD but in their self righteousness they were wrong. When they prayed they didn't even mean what they said because they only wanted others to see the "good works" that they do. All they wanted was for people to like them or to think that they were righteous, and they were willing to murder Jesus for that. That is the difference between obedience and trying to make people think you are obedient by being loud about it. The world needs to figure that out.
