Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
The Lord knoweth them that are his. Wow. When you combine that with what the Lord told the workers of iniquity “I never knew you: depart from me, ye that work iniquity” (Matthew 7:23) it is very clear there are those the Lord knows and those He doesn’t.
The Lord knoweth them that are his. It is NOT: those that know Him, or think they know Him. A man may claim to be a Christian, he may have prayed to accept Jesus, he may have walked the aisle, in Jesus’ Name he may have done many wonderful works, or preached and even cast out demons - but if he does not belong to Jesus, standing in front of the Great White Throne Judgment he will hear those dreadful words “I never knew you: depart from me, ye that work iniquity.” God hates the workers of iniquity - not the iniquity, but the workers thereof (Psalm 5:5).
The Lord knoweth them that are his. He knows only those the Father has given Him, and those the Father has given Him WILL come to Him (John 6:37). Who are those the Father has given Him? His Elect. Those who were chosen and placed in Christ before the foundation of the world (Ephesians 1:4). These are they for whom He shed His Blood and died. (Mark 14:24, Ephesians 5:25)
The Lord knoweth them that are his.
