My understanding:
God expresses new words in the last days. Every brother and sister who accepts God's new work is already experiencing the judgment work by God’s word and our corrupt dispositions have been gradually cleansed by the word of God. What's more, we know more of God’s righteous disposition and we have a God-fearing heart. This is just the group of people of the kingdom that God intends to perfect. Just like what the hymn "The Holy Kingdom Has Appeared" sings. Thank and praise God!
I
The just Sun shines over all the lands,
restores all living things.
God's people gather with joy,
to praise His great achievements.
All lands they dance, sing, cheer.
All things with breath come to praise,
praise to the victory
and the coming of God's day.
The entire universe is new
and cheering loud for God
and for His holy day.
