Serving must become a Spiritual Discipline. The flesh connives against its hiddenness and sameness. Two of the deadliest of our sins – sloth and pride – loathe serving… If we don’t discipline ourselves to serve for the sake of Christ and His Kingdom, we’ll “serve” only occasionally or when it’s convenient or self-serving. The result will be a quantity and quality of service we’ll regret when the Day of Accountability for our service comes.
