As the end draws closer it'll become harder to discern, in some respects, the real Christian vs the illusionary Christian. The real will live on the foundation that it is God who sent and His son who redeems. The Christian who lives the illusionary life will be aware of that, but still try and gain heaven by their own virtue and effort. I use the word "illusionary" because even the one who has fallen victim may not realize what they are doing, and why many on that day will very boldly go before the Lord and attempt to claim what is their inheritance...but will hear the words "Go from me, I never knew you." I have no intention of meeting God with any arrogant proclamation of God to fulfill His promise of what He owes me. For if I ask for what I am owed, then I will burn in the fires of hell. I will seek rather His mercy and pray He remembers this fragile frame and that He remembers those whom He knows.
"Go from me, I never knew you." is forever.
