Atheism is immaturity and overweening pride. They may have high IQs, but it’s useless until they grow up and get over themselves.
The wisest bow before GOD.
Let’s not be too quick to dismiss this study or ones like it. Why do I say this? Yes, the lost and anti God crowd will always try to spin things their way. It’s also true that most people tend to do research not to discover truth but to merely confirm their own presuppositions (atheists and believers alike). However, let’s remember what the scriptures state in 1 Corinthians 1:26-29
26 For consider your calling, brethren, that there were not many wise according to the flesh, not many mighty, not many noble; 27 but God has chosen the foolish things of the world to shame the wise, and God has chosen the weak things of the world to shame the things which are strong, 28 and the base things of the world and the despised God has chosen, the things that are not, so that He may nullify the things that are, 29 so that no [c]man may boast before God.
It doesn’t say “not any” but their numbers will be fewer than in the world at large. In the final judgement “smarts” will not matter that much but as several have already stated here - a humble heart and faith in an almighty God will be what really counts. And on that day God will shame those that really were smarter than the average bear but lacked the faith to believe in the message of the cross and Christ and his finished work. So... for those that will not believe, let them have this moment - as that’s all they will get.
