Interesting, it seems again we have an answer in which it's intelligence which is the deciding factor.
Apparently minimal inelegance (that of a first-grader) is enough; therefore all non-Christians are dumber than a first-grader.
Would you say that in an effort to evangelize, we focus on educating people and honing their intellects, so that they will choose to become Christians?
Since you question my scenario, I'll ask this.
If you got indigestion from eating onions, and went to a physician, what would he tell you?
And what do you think the Great Physician would tell someone who receives condemnation from sinning? No need to wonder about this; Jesus gave us the answer.
Luke 5
31 Jesus answered and said to them, “Those who are well have no need of a physician, but those who are sick. 32 I have not come to call the righteous, but sinners, to repentance.
The answer is repentance. If anyone is a sinner, and is called, he is called to repentance. If repentance is not for one, then his righteousness will be enough so he does not need a physician.
Now let's look at some passages which tell us about repentance and sin.
1 Kings 8:47
yet when they come to themselves in the land where they were carried captive, and repent, and make supplication to You in the land of those who took them captive, saying, ‘We have sinned and done wrong, we have committed wickedness’;
Ezekiel 18
30 “Therefore I will judge you, O house of Israel, every one according to his ways,” says the Lord God. “Repent, and turn from all your transgressions, so that iniquity will not be your ruin.
31 Cast away from you all the transgressions which you have committed, and get yourselves a new heart and a new spirit. For why should you die, O house of Israel?
Mark 1:4
John came baptizing in the wilderness and preaching a baptism of repentance for the remission of sins.
Luke 15:10
Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents.
Luke 17:3
Take heed to yourselves. If your brother sins against you, rebuke him; and if he repents, forgive him.
Luke 24:47
and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem.
Acts 3:19
Repent therefore and be converted, that your sins may be blotted out, so that times of refreshing may come from the presence of the Lord,
Some say we are forgiven all our sins and have not need to repent. Maybe this is why the book of Revelation is not read, nor believed. This book is written to the believers in churches, not unbelievers, to the sheep, not goats, to the elect, not those who aren't elect.
Revelation 2:5
Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place—unless you repent.
Revelation 2:16
Repent, or else I will come to you quickly and will fight against them with the sword of My mouth.
Revelation 2:21
And I gave her time to repent of her sexual immorality, and she did not repent.
Revelation 2:22
Indeed I will cast her into a sickbed, and those who commit adultery with her into great tribulation, unless they repent of their deeds.
Revelation 3:3
Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you.
Revelation 3:19
As many as I love, I rebuke and chasten. Therefore be zealous and repent.
So jimmy, you ask,
'what is different about you in your actions, thoughts or desires, etc., that makes you a Christian while they are not?' There's your answer - repentance and ridding ourselves of sin.
