Matt 7:23 23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. This statement means that He never knew them as His Sheep, remember what He says of them here Jn 10:14 14 I am the good shepherd, and know my sheep, and am known of mine. 15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. Now the word know in Jn 10:14 and the word knew in Matt 7:23 are the very same greek word ginōskō and denotes a knowing in intimacy ! This denotes He never Loved them affectionately as a Husband Loves His Wife ! Now it also means that Christ never knew them to be part of His Wife, the Bride of Christ, for instance in Revelation we read Rev 19:7 7 Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready. Rev 21:9 9 And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife. The Lamb is none other than the Lord Jesus Christ Jn 1:29, and remember John the baptist said of this very same Lamb Jn 3:29 29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled. Note: John represents the OT Hope and so this statement evidences the OT Saints and the NT Saints belonging to the same Bride/Wife of the Lamb ! The Bride and the Wife are one and the same Rev 21:9 And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife. And the Bridegroom/Husband must know His Wife, like it says of Adam the type of Christ Gen 4:1 And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the Lord. This is vitally important because Adam and Eve are a Type, a picture of Christ and the Church Eph 5:30-32 30 For we are members of his body, of his flesh, and of his bones. 31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. 32 This is a great mystery: but I speak concerning Christ and the church. Christ knew and Loved the Church as His Wife and gave Himself for it Eph 5:25 25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it; The Church here is being indicated as the Wife of Christ, the Lamb or the analogy would be useless for Paul to use ! So for Christ to say I never knew you, means He never knew them to be part of His Wife, His Bride of which Hes the Bridegroom of Jn 3:29, whom He gave Himself for !
