Poor in Spirit
“The way to deeper knowledge of God is through the lonely valleys of soul poverty and abnegation of all things. The blessed ones who possess the Kingdom are they who have repudiated every external thing and have rooted from their hearts all sense of possessing. These are the ‘poor in spirit'”
The Pursuit of God, 23

Potential
“I find that many men and women are troubled by the thought that they are too small and inconsequential in the scheme of things. But that is not our real trouble — we are actually too big and too complex, for God made us in His image and we are too big to be satisfied with what the world offers us!
….Man is bored, because he is too big to be happy with that which sin is giving him. God has made him too great, his potential is too mighty.”
Who Put Jesus on the Cross, 170.

“When our Lord looked at us, He saw not only what we were — He was faithful in seeing what we could become! He took away the curse of being and gave us the glorious blessing of becoming.
Who Put Jesus on the Cross, 166”

Prayer
All things being equal, our prayers are only as powerful as our lives. In the long pull we pray only as well as we live. Some prayers are like a fire escape, used only in times of critical emergency — never very enjoyable, but used as a way of terrified escape from disaster. They do not represent the regular life of the one who offers them; rather are the unusual and uncommon acts of the spiritual amateur.

The Root of the Righteous, 81.

“Prayer is never an acceptable substitute for obedience. The sovereign Lord accepts no offering from His creatures that is not accompanied by obedience. To pray for revival while ignoring or actually flouting the plain precept laid down in the Scriptures is to waste a lot of words and get nothing for our trouble.”
Of God and Men, 52.

“When I am praying the most eloquently, I am getting the least accomplished in my prayer life. But when I stop getting eloquent and give God less theology and shut up and just gaze upward and wait for God to speak to my heart He speaks with such power that I have to grab a pencil and a notebook and take notes on what God is saying to my heart.”
Success and the Christian, 46-47

Pursuit of God
“Our pursuit of God is successful just because He is forever seeking to manifest Himself to us.”
Pursuit of God, 65.

To have found God and still to pursue Him is the soul’s paradox of love, scorned indeed by the too-easily-satisfied religionist, but justified in happy experience by the children of the burning heart.
The Pursuit of God, 14
