Romans 1:20 HCSB

For His invisible attributes, that is, His eternal power and divine nature, have been clearly seen since the creation of the world, being understood through what He has made. As a result, people are without excuse.

I believe this scripture negates the idea that one who does not hear the gospel cannot choose against God. If what you are saying is correct I am making the assumption that you also believe adults in the corners of the world where the gospel has not reached also got to heaven?
