We need to be coronary Christians, not adrenal Christians. Not that adrenaline is bad. It gets me through lots of Sundays. But it lets you down on Mondays. The heart is another kind of friend. It just keeps on serving—through good days and bad days, happy and sad, high and low, appreciated and unappreciated. It never lets me down. It never says, "I don't like your attitude, Piper, I'm taking a day off." It just keeps humbly lubb-dubbing along. Coronary Christians are like the heart in the causes they serve. Adrenal Christians are like adrenaline—a spurt of energy and then fatigue. What we need in the cause of racial justice and justice for the unborn is coronary Christians. Marathoners, not just sprinters. People who find the pace to finish the race.
