Be purified, made spotless and refined

Daniel 12:8-13
Many will be purified, made spotless and refined, but the wicked will continue to be wicked. None of the wicked will understand, but those who are wise will understand.
From the time that the daily sacrifice is abolished and the abomination that causes desolation is set up, there will be 1,290 days. Blessed is the one who waits for and reaches the end of the 1,335 days. 
You will rest, and then at the end of the days you will rise to receive your allotted inheritance. 
Not even Daniel understands this - so cautious(謹慎) approach to these matters may still be the wisest course!
Why?
Wicked will continue to be wicked, so don't surprise it and worry about it.
Only wise will understand, it is sealed by the Lord, what we have to do is cautious approach to these matters, be purified. made spotless and refined.
Daniel may rise and receive his allotted inheritance. For he is good servant before the Lord!
How?
Be purified, made spotless and refined in my life. Don't worry about the future and unknown.
