“Manifestation is a deeper part of confession”
We must understand that sons are not known by the world, but what will announce the Sons to the creature is the manifestation of the Sons of God. Not just by saying I am the Son of God, but manifesting it will make it known. Of course God’s word made it clear that we are Sons of God and because Sons are not recognized by the world, just like Jesus was never acknowledged to be a Son of God, we must expect the same.
1John 3:1 Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
3:2 Beloved, NOW are we the sons of God…”
It’s clear that we are the Sons of God but we are not know by the world as sons hence a need for the manifestation of our Sonship.
Romans 8:19 For the earnest expectation of the creature waiteth for the manifestation of the sons of God.
Manifestation is of greater value to the world than our confession. Our confession is to assure us and make us stay on the truth of what has been done for us, but our manifestation talks about our full prove to the world or creature as Sons of God.
