Sermon Posted: “That’s a ‘When’ When It Comes to Fasting” (Matthew 6:16-18)

I am thankful for the wonderful response to God’s Word, especially in regards to the issue of fasting.  This sermon was preached on Sunday, September 28, 2008 at Boone’s Creek Baptist Church, Lexington, KY.

Here’s an excerpt:

David Legge noted in a recent sermon that “Prayer is attaching yourself to God, but fasting is detaching yourself from the earth.” Whatever definition you want to put on fasting, few would equal that one. It is a renewed focus away from the things of earth It is a humbling of yourself before God, bringing your body into subjection through discipline.

These particular verses really turned the focus of what fasting was about in transitioning from the Old Testament to the New. In the Old Testament, the Jewish people celebrated various Holy Days. For instance, on Yom Kippur (the Day of Atonement) there would be a day of fasting and mourning over their own sins and the sins of a nation. The sacrifices offered that day were scene as ways that they may be reconciled to God for their sins. This served as the only time in the OT on which the people of Israel were commanded directly to fast.

Yet other fasts cropped up. We read about them in Joel when national disasters took place. Nineveh fasted after hearing the reluctant preaching of Jonah. Fasting even took place under Samuel as a part of national revival.

Yet for the most part, fasting prior to Jesus’ time was about repentance of sin that transformed the covenant child into selfless human being. Fasting would be undertaken in order to sacrifice for repentance of sin and looking outward for justice among the people. Look at this passage in Isaiah 58:1-7:

Does this mean Jesus did not care for food? Hardly! In fact, the biggest condemnation the Pharisees gave to Jesus was that he eats and drinks with tax collectors and sinners. His most amazing miracle to us is his feeding of the five thousand (Matthew 14:13-21). His focus was on his soul and mind being galvanized to the will of His Father, dependent on nothing in the meantime.

“Cry aloud; do not hold back; lift up your voice like a trumpet;

declare to my people their transgression,

to the house of Jacob their sins.

Yet they seek me daily

and delight to know my ways,

as if they were a nation that did righteousness

and did not forsake the judgment of their God;

they ask of me righteous judgments;

they delight to draw near to God.

‘Why have we fasted, and you see it not?

Why have we humbled ourselves, and you take no knowledge of it?’

Behold, in the day of your fast you seek your own pleasure,

and oppress all your workers.

Behold, you fast only to quarrel and to fight

and to hit with a wicked fist.

Fasting like yours this day

will not make your voice to be heard on high.

Is such the fast that I choose,

a day for a person to humble himself?

Is it to bow down his head like a reed,

and to spread sackcloth and ashes under him?

Will you call this a fast,

and a day acceptable to the Lord?

“Is not this the fast that I choose:

to loose the bonds of wickedness,

to undo the straps of the yoke,

to let the oppressed go free,

and to break every yoke?

Is it not to share your bread with the hungry

and bring the homeless poor into your house;

when you see the naked, to cover him,

and not to hide yourself from your own flesh?

Yet, with Jesus, the issue of fasting became very different. We see in Matthew 4 that Jesus went out and fasted for 40 days and 40 nights. Why? Was it for repentance of sin? We know from Scripture and from clear reason that Jesus never sinned (Hebrews 4:14-16; 2 Corinthians 5:21). So what was he doing? One commentator put it so rightly, “He was gathering strength not by eating and resting but by fasting and praying.”

Yet did Jesus seem outwardly strengthened? No, not at all. In fact, Satan tempted him with food and fame and fortune—the very things that Jesus would have struggled with to get him out of his situation. But he said no. Clearly, through his responses to Satan, he found himself feasting on prayer and the Word.

How Long Is Too Long for a Sermon?

One of the standard jokes we have here at Boone’s Creek is the length of my sermons. I tend to preach about 35 minutes on average, which is a bit longer than some. I preach expositionally, which means that whatever the theme of the text is becomes the theme of my sermon. Whatever structure the biblical text is becomes the structure of the sermon. The Holy Spirit laid out the Scriptures this way, so who am I to do otherwise?

But getting back to the “joke,” we have some folks in our church who grew up with a preacher who preached two hours or more. Others grew up with a sermon lasting only 15 minutes or so. In fact, I had one person tell me a number of years ago, “If you preach past 12:00, they’ll tune you out” (this was after a Trinidadian preacher visited us and preached a God-glorifying sermon, but went until 12:30).

John MacArthur has a wonderful article entitled “Preaching and the Clock” (website/pdf) which begins as follows:

I do not think the length of the sermon is as important as its content. At times I have preached fifty minutes and it has been ten minutes too long. Other times, I have preached an hour and twenty-five minutes and it has been just right. The important thing is to cover the main point so that people are convinced of its truth and comprehend its requirements.

If you have nothing worthwhile to say, even twenty minutes will seem like an eternity to your people. If you are interesting, they will stay with you. Do not mistake persuasion for long-windedness, however. If you preach longer than you should, you will sacrifice persuasiveness.

Now, I will confess freely that I do not preach like MacArthur. God has not called me to preach like John MacArthur (God already gave us one of him), but to preach in the Spirit and His Word using me as his earthen vessel. Even so, I do understand that even with me preaching 35 minutes or so, I am just barely scratching the surface of what the Word is saying.

And fortunately for me, I do not have a “one-and-done” situation– I will have other Sundays! But I am with MacArthur: as a preacher, make sure your people know the principle of the passage on which you preach so they may grow in Christlikeness.
