No discipline seems enjoyable at the time, but painful. Later on, however, it yields the peaceful fruit of righteousness to those who have been trained by it. Hebrews 12:11 CSB

Discipline yourself to prayer. Discipline yourself to the systematic reading of the scripture from Genesis to Revelation, over and over and over again. Discipline yourself in your speech. Discipline yourself in the company you keep. Discipline yourself in when you go to bed and when you rise up. This is war. Discipline yourself. Uncertain Attribution (Note 1)
