2 Corinthians 3:8-9 8How shall not the ministration of the spirit be rather glorious? 9For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory. (2 Cor. 3:8-9 KJV)

Moses spent long, uninterrupted time with God. He fasted throughout this period of 40 days and 40 nights on the Mount. Fasting is an exercise of self-humiliation, not for self-interest, but for God’s glory; not for legalistic asceticism, but an act of loving service to render the body more susceptible to the higher interests of the soul in the worship of God. In fasting, we do not have to be about the task of caring for the meal but have unbroken time with God.

Such self-humiliation would have been highly profitable and would be according to the teachings in the New Testament: 1 Corinthians 10:31, “Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.”
