“Those who have insight will shine brightly like the brightness of the expanse of heaven, and those who lead the many to righteousness like the stars forever and ever.” (Daniel 12:3)
“Many will be purged, purified and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have understanding will understand.” (12:10)
I love the cryptic, yet concrete wording of Daniel. It is like much of the wording of poetry. What I have taken from Daniel above is actually taken out of context in that an angel is speaking to Daniel about the last days. And yet the words put clearly the way of the Lord and those who follow him in every generation.
The Lord works in his people, using them to proclaim his righteousness, while they are used by the Holy Spirit to lead many out of the darkness of this age into the righteousness of Jesus Christ.
But there are those who, in their wickedness, no matter how hard one knocks upon the door, cannot hear.
And yet—the Holy Spirit is there wooing, pleading, convicting. And we must be there also, praying, pleading.
