Does Jesus literally mean He never knew the sinners, even those who called upon Him? God is all-knowing but does this verse mean by His own Divine mystery He only knows some of His children - those baptized into Christ with water and Spirit AND live His teachings (do good works in His Name, charity, and live the Faith)?
Would this explain why many Catholics ask Blessed Mary to intercede for them, and their prayers are answered because she knows us, and her Son will do what she asks of Him, if for His greater glory and to show that He is real), but in the end, same Catholics will perish for eternity because, ultimately, they were wicked, hence, Jesus Christ never knew these people? Would this explain the meaning of the names written in the Book of Life mentioned in Revelation? God only knows those souls who are written in that Book?
