There can be no doubt that this possessive clinging to things is one of the most harmful habits in the [christian] life. Because it is so natural, it is rarely recognized for the evil that it is. But its outworkings are tragic.
Whoever has Christ in his heart, so that no earthly or temporal things — not even those that are legitimate and allowed — are preferred to Him, has Christ as a foundation. But if these things be preferred, then even though a man seem to have faith in Christ, yet Christ is not the foundation to that man.
