Why would they do that? Because they loved darkness more than the light, perhaps?
They have to hear....which is why we preach the gospel. It's the power of God unto salvation for all who hear and believe. There is power in God's word that we were created to hear.
When you slip in something that isn't true, it nullifies your conclusion. God created us to know Him. You already agreed to that..
Hear Paul tells us there are Gentiles who "do by nature" the things contained in the law.....their God given (conscience) bears witness. Our conscience is awakened by the word of God...which is why the Gospel is the power of God unto salvation. How can they believe unless they hear? How can they hear without a preacher? You seem to think that they can't hear with or without a preacher. :think:
Romans 2:14-15
For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing
So when the light of the glorious gospel shines, and we hear the word of God, we remember God's goodness, longsuffering, and forbearance in our lives which causes us to turn to Him and trust Him. That's what happened to me.
Romans 2:4 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
