Secular liberal gaytheists like to think that Einstein was smart, but True Christians know better. You see, God used Einstein as a tiny little cog in God's Great Wheel. God wanted His Blessed country to have the bomb, and so He gave Einstein a tiny bit more intelligence in order to let Einstein do the equations. As Einstein was a mere human and unable to see God's Grand Design, only too late did he realize what he had given us. Being a liberal infidel, Einstein lamented it later, thus showing his true impious colors by expressing regret at doing God's work. God had the last laugh on Einstein, as He does on all those who deny God's Plan.
Jer 29:11
For I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil, to give you an expected end.
Glory onto Him.
