Epistles: Ephesians 4:17-32 – The Call to Good Conduct in Christ


Key text: “So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking… You, however, did not come to know Christ that way. Surely you heard of him and were taught in him in accordance with the truth that is in Jesus” (Ephesians 4:17, 20-21).

Lesson objective: To understand that every believer is called to the same high standards of conduct worthy of their honored position in Christ. True believers are to “walk the talk” and bind belief with Christian moral conduct to God’s glory.

Introduction: Changes in one’s routine of life are among the most stressful times in any person’s life. Even joyous occasions, such as planning a wedding, or a newborn’s arrival into the family, are difficult adjustments. Stress points are added when a person leaves home and when one takes on a new job or changes careers in mid-stream. Also, times are hectic when one buys a home or has to move to another area. Of course, there are the more challenging times, when one loses employment or when divorce is imminent or when a loved one passes on. Certainly more can be added to the list, such as loss of health, etc. But among the most mysterious and wondrous changes of all is a person’s conversion to Christ. It is remarkably joyous but stressful as well.

A person’s philosophy of life and personality are often radically altered upon conversion. One was traveling 100 miles per hour in one direction and is suddenly pulled in the opposite direction. An encounter with the living Christ is a life-altering event. In Ephesians, Paul reminds his readers of that fact (4:17-24). They are not who they used to be! In the world today, the philosophy of life seems to be “take what you can get and roll over anyone who gets in your way” or “use persons to your own advantage and whenever they become a liability, dump them!” But this kind of thinking is futile, short-sighted, and in the end can only spell disaster. It matters not how much power, sensuality or wealth you accumulate or how you did it, in the end it is all staying behind! There is no hope without Christ. For this reason, Paul urges believers to leave the “old self” behind and be clothed with the “new self” in Christ.

Believers in Christ speak the truth, seek out reconciliation and share what they have received, while the world thrives on falsehood, anger and stealing in one form or another (vv. 25-32). A true Christian is known by his or her good speech and kindness toward others, while many today spew out foul language like a turned-on fire hydrant, and they are not even aware of it! It should be no surprise that this world is plagued with ever-increasing hatred and animosity among nations, races and even religions! For the disease is in the sinful condition of a heart that knows not Christ.

God’s plan in Christ is to bring every believer’s moral conduct in line with the high position in Christ to which he has called the person. And this means living out the Christian life in the here and now, no matter what the stress! Our philosophy of life is to treat others as we would like to be treated (Matthew 7:12), even when they treat us badly! And we believe Jesus when he said: “It is more blessed to give than to receive” (Acts 20:35). And while none of us will be perfect in this life, for Christ is our perfection, yet God has set a goal of godly moral conduct for the sanctification of the members of his church; he has changed their lives through the cross and via the Holy Spirit, to his glory!
