If the Lord Jesus has died for the sin of the whole world, as you suggest, then there are no guilty. There is no one that would not go into the Kingdom of God. Even those who don't want to.
They have all been cleaned by the Blood of Christ.
Universalism, in a nutshell. Everyone is saved. No one needs to come to Christ or receive anything. They already have it.
Revelation 7:13-15
13 And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?
14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
15 Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
As proof I proffered John 1:29. I know you do not mean to, but now becomes your word against that of the Almighty.
Romans 5:12.
"Wherefore, as by one man sin (singular) entered into the world, and death by sin (singular); and so death passed upon all men, for that all have sinned:"
Of this "sin" that is NOT committed, but passed on to all men (except Jesus),
John 1:29 says;
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin (singular) of the world."
Next, you again unwittingly go against the Almighty Who does NOT impose guilt for "sin" (singular).
Romans 5:14 says;
"Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come."
This in turn again leads you to go against the Words of scripture. You make the removal of sin the ground for entering the Kingdom. But scripture says in
John 3:3-5 that a man must be born again to SEE it, and born out of the Spirit and Water to ENTER it. It is true that certain behavior can exclude one from the Kingdom, but these are "sinS" (plural), or "trespasses", not "sin" inherited from Adam.
Adam sinned. It polluted his body and character. This is his transgression. Because God made a law of procreation in Genesis 1:12-13, every one that proceeds from Adam's loins is polluted. This is what scripture calls "sin" (singular). That's why
Psalm 51:5 says:
"Behold, I was shapen in iniquity; and in sin did my mother conceive me."
Our Lord Jesus dies for this matter, not so that men might escape the Lake of Fire, but so that they can be resurrected - for the wages of sin (singular) IS DEATH - not the Lake of Fire.
In light of this, I'm sure you will rethink the matter.
