Dallas Willard said this quote

The first fruit of love is the musing of the mind on God. He who is in love, his thoughts are ever upon the object. He who loves God is ravished and transported with the contemplation of God. When I awake, I am still with thee (Psalm 139:18). The thoughts are as travelers in the mind. David's thoughts kept heaven-road. I am still with Thee. God is the treasure, and where the treasure is, there is the heart. By this we may test our love to God. What are our thoughts most upon? Can we say we are ravished with delight when we think on God? Have our thoughts got wings? Are they fled aloft? Do we contemplate Christ and glory?... A sinner crowds God out of his thoughts. He never thinks of God, unless with horror, as the prisoner thinks of the judge.

The cautious faith that never saws off a limb on which it is sitting, never learns that unattached limbs may find strange unaccountable ways of not falling.

We live in a culture that has, for centuries now, cultivated the idea that the skeptical person is always smarter than one who believes. You can almost be as stupid as a cabbage as long as you doubt.

~ Dallas Willard

Spirituality has thus come to be regarded by the world as those futile, self-torturing excesses of strange men and women who lived in far-off, benighted places and times. Accordingly, the One who came to give abundance of life is commonly thought of as a cosmic stuffed shirt, whose excessive spirituality probably did not allow him normal bodily functions and certainly would not permit him to throw a frisbee or tackle someone in a football game.
