Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.” - John 3;3, NIV.

"...but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles..." - 1 Corinthians 1:23, NIV.

So, Christianity might only become "logical" after one is born again. In my opinion ,Scriptures indicate never will anyone see Heaven by intellectual ascent.

Not for nothin'.
