23 For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24 and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25 In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” 1 Cor 11:23–25, NASB
23 “Am I a God who is near,” declares the LORD, “And not a God far off? 24 “Can a man hide himself in hiding places So I do not see him?” declares the LORD. “Do I not fill the heavens and the earth?” declares the LORD. 25 “I have heard what the prophets have said who prophesy falsely in My name, saying, ‘I had a dream, I had a dream!’ 26 “How long? Is there anything in the hearts of the prophets who prophesy falsehood, even these prophets of the deception of their own heart, 27 who intend to make My people forget My name by their dreams which they relate to one another, just as their fathers forgot My name because of Baal? Jer 23:23–27, NASB
Man is a fallen creature. He is flawed. He is forgetful. He is self-focused. He is incapable of knowing God without His divine intervention.
19 Then Joshua said to the people, “You will not be able to serve the LORD, for He is a holy God. He is a jealous God; He will not forgive your transgression or your sins. 20 “If you forsake the LORD and serve foreign gods, then He will turn and do you harm and consume you after He has done good to you.” Josh 24:19–20, NASB
There are only two groups of people. There are those who are known by God, are regenerate, have their sins covered by the blood of the Lamb, and are Holy unto the Lord. The other group are those not known by God. They are unregenerate and are in their sins. They are of the World. These two groups are totally separate from one another on the Spiritual plane, but intermingled with one another on the Temporal plane. The first group has received that divine intervention and are now able to serve the LORD. The best the second group can do is be religious and their works unto the Lord are as filthy rags.
