From Doctrine to Duty

A devotional by Grace To You for reading on January 3rd

“I, therefore, the prisoner of the Lord, entreat you to walk in a manner worthy of the calling with which you have been called” ( Ephesians 4:1 Chapter 4 1 I therefore, the prisoner in the Lord, beseech you to walk worthily of the calling wherewith ye were called, ).

There can be no right living without right principles.

Imagine someone saying, “I have some extra money lying around. I think I’ll send a large check to the government.” Absurd, isn’t it? But every year, honest wage-earners fill out forms and give part of their income to the government. Why? It’s not because they are generous but because there is a law— a doctrine—that says they have to.

Unless people know the reason for what they should do, it’s unlikely they’ll make a commitment to do it. Paul understood that, so he always taught doctrine before duty. “Therefore” in Ephesians 4:1 Chapter 4 1 I therefore, the prisoner in the Lord, beseech you to walk worthily of the calling wherewith ye were called, links the doctrine of chapters 1—3 to the duty of chapters 4—6. Doctrine and duty are inseparably linked; duty always flows out of doctrine. Right living is based on right principles. Paul told the Colossian church, “We have not ceased to pray for you and to ask that you may be filled with the knowledge of His will in all spiritual wisdom and understanding” (1:9). For what purpose? “So that you may walk in a manner worthy of the Lord” (v. 10). Spiritual knowledge, wisdom, and understanding make up the pathway of a worthy walk.

When pastors teach duty without teaching doctrine, they weaken the Word of God because they’ve eliminated the motive. They may be able to stir up emotions, but that brings no long-term commitment. The pastor’s responsibility is to teach the truth of God, and the hearer’s responsibility is to obey it.

Of course, the source of God’s truth is His Word: “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; that the man of God may be adequate, equipped for every good work” (2 Tim. 3:16-17). Knowing the Bible well is our means of equipping ourselves for a righteous life.

As we think about our worthy walk, let’s avoid emotionalism and legalism, and instead focus on living what we learn from a thorough and personal study of God’s Word.

Suggestions for Prayer

If you have neglected studying the Bible, confess that to God, and ask Him to give you a greater desire to learn His Word.

For Further Study

Read Ephesians 1 Chapter 1 1 Paul, an apostle of Christ Jesus through the will of God, to the saints that are at Ephesus, and the faithful in Christ Jesus: 2 Grace to you and peace from God our Father and the Lord Jesus Christ. 3 Blessed `be' the God and Father of our Lord Jesus Christ, who hath blessed us with every spiritual blessing in the heavenly `places' in Christ: 4 even as he chose us in him before the foundation of the world, that we should be holy and without blemish before him in love: 5 having foreordained us unto adoption as sons through Jesus Christ unto himself, according to the good pleasure of his will, 6 to the praise of the glory of his grace, which he freely bestowed on us in the Beloved: 7 in whom we have our redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, 8 which he made to abound toward us in all wisdom and prudence, 9 making known unto us the mystery of his will, according to his good pleasure which he purposed in him 10 unto a dispensation of the fulness of the times, to sum up all things in Christ, the things in the heavens, and the things upon the earth; in him, `I say,' 11 in whom also we were made a heritage, having been foreordained according to the purpose of him who worketh all things after the counsel of his will; 12 to the end that we should be unto the praise of his glory, we who had before hoped in Christ: 13 in whom ye also, having heard the word of the truth, the gospel of your salvation,-- in whom, having also believed, ye were sealed with the Holy Spirit of promise, 14 which is an earnest of our inheritance, unto the redemption of `God's' own possession, unto the praise of his glory. 15 For this cause I also, having heard of the faith in the Lord Jesus which is among you, and the love which `ye show' toward all the saints, 16 cease not to give thanks for you, making mention `of you' in my prayers; 17 that the God of our Lord Jesus Christ, the Father of glory, may give unto you a spirit of wisdom and revelation in the knowledge of him; 18 having the eyes of your heart enlightened, that ye may know what is the hope of his calling, what the riches of the glory of his inheritance in the saints, 19 and what the exceeding greatness of his power to us-ward who believe, according to that working of the strength of his might 20 which he wrought in Christ, when he raised him from the dead, and made him to sit at his right hand in the heavenly `places', 21 far above all rule, and authority, and power, and dominion, and every name that is named, not only in this world, but also in that which is to come: 22 and he put all things in subjection under his feet, and gave him to be head over all things to the church, 23 which is his body, the fulness of him that filleth all in all. —3 and list all we are or have in Christ. Knowing what God has given you, can you do any less than commit yourself to Him completely?
