If His hidden agenda intervened, why didn’t Paul know about it?
Especially since that “hidden agenda“ involved Paul.
I have no idea what you're talking about.
The hidden agenda was the dispensation of the grace of God given to Paul.
So of course Paul knew about it.
Eph 3:8-12 (AKJV/PCE)
(3:8) Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; (3:9) And to make all [men] see what [is] the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: (3:10) To the intent that now unto the principalities and powers in heavenly [places] might be known by the church the manifold wisdom of God, (3:11) According to the eternal purpose which he purposed in Christ Jesus our Lord: (3:12) In whom we have boldness and access with confidence by the faith of him.
What is a lie? Didn‘t you watch that video Clete put up?
You should because the answer is there.
Jesus was not lying.
