2 Kings 19:25-26 says, "Have you not heard? Long ago I did it; from ancient times I planned it, now I have brought it to pass, that you should turn fortified cities into ruinous heaps. Therefore, their inhabitants were short of strength, they were dismayed and put to shame." These words were spoken by God to Sennacherib king of Assyria in relation to his boasting about the nations that he had overthrown. God is quick to humble him, however, by informing him that those nations were overthrown only because He providentially weakened them. The destruction of these nations was something he had planned long before Sennacherib came on the scene. In other words, Sennacherib should not have boasted about his accomplishments because they were not his.
God operates in the same way in the lives of believers. Ephesians 2:10 says, "For we are His workmanship, created in Christ Jesus for good works, which He prepared beforehand, that we should walk in them." Our good works are planned by God long beforehand and it is He that providentially brings them to pass in our lives and allows us to participate.
Again, I apologize, this post is more devotional than conversational, but I thought the comparison between 2 Kings 19:25 and Ephesians 2:10 was an interesting one.
