Disciplining Yourself for a Purpose

“Bodily discipline is only of little profit, but godliness is profitable for all things, since it holds promise for the present life and also for the life to come” (1 Timothy 4:8).


Godliness should be the believer’s priority in life.

I’m amazed at how devoted people can be to what they believe is important. There are many people outside Christianity who live in rigid conformity to a lot of meaningless rules. People in totalitarian countries, for example, live in rigid conformity to rules predicated on a denial of biblical truth. They walk circumspectly and toe the mark.

Some cultists are so rigid and walk so circumspectly according to the principles dictated to them that if they’re told they can’t get married or can’t be with their spouses, they conform. They’re made to live in abstinence from physical relationships, follow strict diets, fast, and so on. Some attempt to attain spirituality through such self-disciplined acts as lying on a bed of nails or walking through hot coals.

Others, such as athletes, go through tremendous self-discipline through dieting, running, weight training, and other means that involve great sacrifice.

People disciplined in things that are ultimately meaningless may be lax in things that count. I know people who run three miles every day but will not bother to read the Bible regularly. I know other people who cannot discipline themselves to feed on the Word of God but stick rigorously to a diet. Many Christians worship physical fitness and health and are so conformed to the world’s system that they’re careless and lazy about conforming to Christ.

If you are a wise Christian, you’ll be sure to discipline yourself for godliness. You’ll know what pleases God, watch for Satan’s traps, resist the Devil, defeat temptation, and be selective about your behavior. In other words, you’ll not walk as a fool; you’ll walk in wisdom—living by God’s standards.

Suggestions for Prayer
Thank God for His Son, the perfect example of spiritual discipline and godliness. Ask God to help you be like Him.

Playing the Fool

“Behold, I have played the fool” (1 Samuel 26:21).


A Christian should not act like a fool.

In Deuteronomy 32:6 Moses looked out at the belligerent children of Israel who had failed God so many times and said, “Do you thus repay the Lord, O foolish and unwise people?” The children of Israel were playing the fool. Sadly, God’s people today continue to play the fool.

One way they do so is through disbelief. On the road to Emmaus, Jesus appeared to two disciples who didn’t believe that He had risen from the dead. Jesus said to them, “O foolish men and slow of heart to believe in all that the prophets have spoken!” (Luke 24:25). To disbelieve God and His Word is to play the fool.

Another way believers play the fool is through disobedience. In Galatians 3:1 the apostle Paul says, “You foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified?” And in verse 3 he says, “Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?” They started out well but were disobedient and got caught up in the works of the law.

Still another way Christians play the fool is through desire for the wrong things. First Timothy 6:9 says, “Those who want to get rich fall into temptation and a snare and many foolish and harmful desires.” If you desire the wrong things, you play the fool.

Finally, you can play the fool through doing the wrong things. James 3:13-16 says that there are two kinds of wisdom. Godly wisdom produces “good behavior” (v. 13), but foolish wisdom produces “jealousy and selfish ambition” (v. 16). A self-centered person plays the fool.

It’s sad to see so many Christians playing the fool. It doesn’t make any sense. Why should Christians live as blind, ignorant, foolish people when they have the wisdom of God?

Paul says at the end of Romans, “I want you to be wise in what is good, and innocent in what is evil” (16:19). If you have to be a fool at all, be a fool (unknowing, unacquainted) about evil.

Suggestions for Prayer
Make Paul’s exhortation in Romans 16:19 your prayer.

For Further Study
Read Proverbs 2:1-22 as a reminder of what benefits you’ll receive from following true wisdom instead of playing the fool.

Watch Your Step

“Therefore be careful how you walk, not as unwise men, but as wise” (Ephesians 5:15).


Walking wisely is a step in the right direction.

Sometimes a soldier has the thankless task of clearing mine fields from enemy territory. If you’re aware of the procedure, you know the work is both dangerous and tedious. To proceed in an orderly fashion, a soldier marks areas that are considered dangerous and areas that have been cleared. Above all, he makes sure he is careful where he’s walking! In the spiritual realm, Paul is telling believers in Ephesians 5:15 to walk carefully. The Greek term translated “careful” speaks of looking carefully from side to side and being alert to what is going on.

We need to be extremely alert because the world we’re walking through is a mine field of sin and temptation. Therefore, we must walk carefully, exactly, and accurately. The wise Christian carefully charts his course according to life principles designed by God. He doesn’t trip over the obstacles that Satan puts in his path or fall into the entanglement of the world’s system. He is “careful.” The Greek word translated “walk” means “daily conduct,” “daily pattern,” or “daily life.” The daily pattern of our lives must reflect wisdom. The Greeks saw wisdom primarily as head knowledge. They tended to spin off theories that had no practical implications. To them, the wise people were the intellectuals and the philosophers. The Hebrew mind, however, defined wisdom only in terms of behavior. When a person becomes a Christian, it’s more than a change in theory—it’s a change in how he lives.

Paul is saying in verse 15, “If you used to be a fool, but you’ve been made wise in Christ, then walk wisely.” In other words, we’re to practice our position, to live in accordance with who we are. When we became Christians, we came out of foolishness into wisdom. Therefore, we need to act like it!

Be careful not to act foolishly and step on Satan’s mines. Your spiritual transformation demands that you live your life with care.

Suggestions for Prayer
Thank the Lord for helping you obey His Word and avoid Satan’s destructive mines.

Growing in Wisdom

“Grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18).


Growing in wisdom means growing in Christlikeness.

Perhaps you’re asking, “Shouldn’t believers acquire more wisdom?” Yes, we should. No matter how much of God’s wisdom we have, we should always hunger for more. The Bible tells us that we have all the principles we need to walk in wisdom, and yet there’s much more available to us. We should “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18), and we should be more and more conformed to the image of Christ by the transforming work of the Spirit of God. Our wisdom should increase, as should our godliness, but we are given the basic principles at salvation. Even though a person may not know all the truths in the Bible, God’s Spirit, who is resident in him from the moment of salvation, will convict and convince him of righteousness and sin.

What do you do if you want more wisdom? First, worship. Proverbs 9:10 says, “The fear of the Lord is the beginning of wisdom.” Make it your goal to have a worshipful heart throughout each day and to be faithful in attending the Lord’s house regularly (see Heb. 10:25). Second, pray. James 1:5 says, “If any of you lacks wisdom, let him ask of God, who gives to all men generously and without reproach, and it will be given to him.” Make it your continual prayer to ask God for more of His wisdom. Third, receive instruction. The apostle Paul encouraged “admonishing every man and teaching every man with all wisdom” (Col. 1:28). If you want more wisdom, one good way to receive it is to be instructed by someone who is wise. Finally, study Scripture. In 2 Timothy 2:15 Paul says, “Be diligent to present yourself approved to God as a workman who does not need to be ashamed, handling accurately the word of truth.” Set up a regular Bible study time, and let the Holy Spirit teach you.

What about you? Are you growing in wisdom? If not, make it your priority.

Suggestions for Prayer
Ask God to help you grow in wisdom.

Make it your daily goal to implement the four ways mentioned in today’s lesson for growing in wisdom.
