Why is there the complete destruction of the wicked?
is it because of sins...
yes - but in the sense that it is because of the sins against Christ on the cross
Jesus was vindicated in His resurrection...
but His total vindication is the destruction of His accusers
and so the church shares in His vindication - since we are His body
Daniel 6:6-9 6 Then these presidents and satraps came by agreement to the king and said to him, "O King Darius, live forever! 7 All the presidents of the kingdom, the prefects and the satraps, the counselors and the governors are agreed that the king should establish an ordinance and enforce an injunction, that whoever makes petition to any god or man for thirty days, except to you, O king, shall be cast into the den of lions. 8 Now, O king, establish the injunction and sign the document, so that it cannot be changed, according to the law of the Medes and the Persians, which cannot be revoked." 9 Therefore King Darius signed the document and injunction.
Daniel 6:23-24 23 Then the king was exceedingly glad, and commanded that Daniel be taken up out of the den. So Daniel was taken up out of the den, and no kind of harm was found on him, because he had trusted in his God. 24 And the king commanded, and those men who had maliciously accused Daniel were brought and cast into the den of lions- they, their children, and their wives. And before they reached the bottom of the den, the lions overpowered them and broke all their bones in pieces.
thus the complete (or eternal) destruction of the wicked - is based on the Cross of Christ... it is and must be for all eternity - so that He is completely proved righteous
