I remember in my younger days a lot of people knew who I was, but not because then knew me personally; they knew me by association-- they knew others who did know me... that were close to me.
Even still with business I encounter similar situations. Many know who I am but aren't close enough to know me personally. I'm not into popularity. No, I share this because as I pondered these things the Lord spoke to my heart.
He brought this passage to mind:
"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity." Matthew 7:21-23
Many know of Jesus yet very few know Him personally. Key question is: Does He know you?
He said, "Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." Matthew 7:14
Knowing Him is personal. Religion leads one to believe it's collective or a grapevine experience. It is not by customs, traditions nor through any other coattail experience that we are forgiven, redeemed, and set free... Come to know Christ, turn to Him. Only He has the power to save.
Will you be a stranger saying unto Him, "Lord, Lord..." only to hear those dreaded words, "I never knew you" and be eternally cast away?
