It does say in the book of Isaiah though "Come now, and let us reason together..."
To reason together is one thing...to insist on your own opinion is another. This is where satan's influence has spoilt human thinking right at the beginning...WE have this strong URGE to BE RIGHT which is from the devil who is a spirit stronger than ours...THAT is why we NEED the Holy Spirit of God to counter/kill it. Speaking the WORD of GOD will achieve that in ourself and others - for it is 'sharper than a double-edged sword coming out of His mouth Heb 4v12, cutting down and out all opposition'.
Of course what is required of us is OBEDIENCE to Him OF OUR OWN FREE WILL because now we LOVE HIM...not (no longer) because we are commanded...that was OT !!!
So...is everybody rushing to obey God now ? certainly not, because satan does not give up so easy..he has for the time got us (mankind) and he wants to keep us...so he finds other ways around that problem and people under his influence are his ignorant followers...to this day !!!
