I agree with what he says. If you have the law written in your heart and you do what He says you go to heaven.
I was hungry and you gave Me something to eat.
Problem is most atheists don't have the law written in their hearts and need Jesus and if you only tell 'em this, they might think: oh I'm such a good person, I'll go to heaven by my good works, a lot are proud and don't see themselves as sinners.

Romans 2
who will render to each one according to his deeds:[a] 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; 8 but to those who are self-seeking and do not obey the truth, but obey unrighteousnessindignation and wrath, 9 tribulation and anguish, on every soul of man who does evil, of the Jew first and also of the Greek; 10 but glory, honor, and peace to everyone who works what is good, to the Jew first and also to the Greek. 11 For there is no partiality with God.
12 For as many as have sinned without law will also perish without law, and as many as have sinned in the law will be judged by the law 13 (for not the hearers of the law are just in the sight of God, but the doers of the law will be justified; 14 for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, 15 who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them) 16 in the day when God will judge the secrets of men by Jesus Christ, according to my gospel.
