Then if any man shall say unto you, Lo, here is the Christ, or, Here; believe it not.
Matthew 24:23
I didn't ask about a false preacher.
I asked about a true preacher.
I think you asked about Yochanan the immerser, didn't you ?
Why did people follow him ?
Because he was true, and sent by Yahweh, as Yahweh Says, as Yahweh's Word Says.
And Yahweh Says , to those who believe in Him, who trust and rely on Him, who are seeking the Truth and seeking His Governing , His Kingdom,
to
seek out those who are true in faith, and remain with them,
and not to remain with nor seek out those who are false.
If you were seeking the Truth, as the people were who sought out Yochanan the immerser, and if you keep seeking the Truth, and not
to justify your own sinful life,
God's Promise , should you decide to believe Him, is that you will know the Truth, no longer reject the Truth, and the Truth will set you free, you will no longer be under the power of the devil nor of the flesh nor of the world.
