It doesn't say in Revelation that the 10 commandments are in the ark. The ark mentioned there is figurative language for Christ. He is the true ark.
No, the Ark is God's throne, it is topped by the Mercy Seat God sits upon. The comment "It doesn't say in Revelation that the 10 commandments are in the ark." shows the complete ignorance of the poster...

Jer 31:33 But this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people.

The Commandments seemed pretty important to Christ...
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
So, it all boils down to whom you wish to listen to, the poster who hates God's Law, or Jesus Christ Himself.
