I asked you to show some Biblical support for Jesus searching the hearts of all people, but you seem to be conflating Jesus with God. God is the one who gave the message to Jesus to in turn give the message to the church. When Jesus spoke to them, he is informing them about what God said.
For example, after Jesus said what God told him to say, there isn't a verse about Jesus knowing the hearts of all or him chastening people. Chastening comes from God, hence why Jesus was himself chastened. The searching of all peoples' hearts come from God, hence why the Bible doesn't say Jesus searches all hearts.
The crux of your doctrine is that t doesn't have any Biblical support. "I search all the hearts" and " I chasten you" or "I am God" etc aren't things Jesus taught and it isn't something any of the apostles/disciples taught either. There are literally no quotes or actions by Jesus in the Old Testament either.
And yet we still have these gems...
John 12
49I have not spoken on My own, but the Father who sent Me has commanded Me what to say and how to say it. 50And I know that His command leads to eternal life.
So I speak exactly what the Father has told Me to say.”
Revelation 1
1This is the revelation of Jesus Christ, which God gave Him to show His servants what must soon come to pass...
Revelation 2
29He who has an ear,
let him hear what the Spirit says to the churches.
