Acts 12

The Lord said in modern day -

"...in nothing doth man offend God, or against none is his wrath kindled, save those who confess not his hand in all things, and obey not his commandments." (Doctrine and Covenants | Section 59:21)

Herod was a wicked and murderous king whom -

"...stretched forth his hands to vex certain of the church.
2 And he killed James the brother of John with the sword." (New Testament | Acts 12:1 - 2)

But what seemed to bring about his final destruction was when the King of Tyre and Sidon wished to make peace with Herod -

"And upon a set day Herod, arrayed in royal apparel, sat upon his throne, and made an oration unto them.
22 And the people gave a shout, saying, It is the voice of a god, and not of a man." (New Testament | Acts 12:21 - 22)

It seemed this was the straw that broke the camels back -

"And immediately the angel of the Lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost." (New Testament | Acts 12:23)

Where we may fail the most is when we do not confess God's hand in all things.
