God's Existence Is Plain To See

 "There is no one thing whatsoever more plain and manifest, and more demonstrable, than the being of God. It is manifest in ourselves, in our bodies and souls, and in everything about us wherever we turn our eye, whether to heaven, or to the earth, the air, or the seas. And yet how prone is the heart of man to call this into question! So inclined is the heart of man to blindness and delusion, that it is prone to even atheism itself.” 
Jonathan Edwards

Spurgeon adds, “He who hates truth soon hates its advocate.”
