You never heard that from a Calvinist CTD.
Once the grace of God falls on a man his desire is for God and God alone.The unregenerate prefer to be their own Lord.
Those that have been Born again prefer Jesus as Lord and not themselves.
I think you may have misread it..Some men that are currently unregenerate , will be saved in Gods time.
1Cr 12:3 Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and [that] no man can say that Jesus is the Lord, but by the Holy Ghost.
