Could it be that we are talking about two different things? That is why MST keeps talking about bible idolatry? We may be all on the same page, but not focusing on the same paragraph.
Anyone....and I mean anyone, can hear from God. Once a person ponders the creation of the universe and realizes that there had to be someone who planned all of it from the beginning and wishes to know the true Creator...may know Him, for God wishes to be known.
But...we are talking about knowing the Word....Jesus. Pondering the universe does not teach about Jesus...it only teaches about God. The bible is not Jesus, but it is the words that God wanted mankind to know about His Son.
One must hear the words of the gospel to know about the Word of God, which is Jesus. Then one must maintain that good gospel word that opens one's heart, by the power of the Holy Spirit, to become the Word that lives within them.
