Introduction: Understanding the Text
In Deuteronomy 5:22, Moses reminds the people of Israel of the Law given at Mount Sinai, saying, “These words the Lord spoke to all your assembly at the mountain from the midst of the fire, of the cloud, and of the thick gloom, with a great voice, and He added nothing more.” This verse highlights the finality and sufficiency of God’s revelation to His people at that time. Moses emphasized that God gave the Law in its entirety, and no one was permitted to add to or take away from it.
This principle of God’s completeness applies not only to the Law but also to His overall revelation throughout history. As we will see, the New Testament reiterates that God’s Word is sufficient, and humanity must neither add to it nor diminish it. This article explores the sufficiency of God’s Word in various aspects of Christian faith and practice.
God Added No More to His Law
The Israelites were explicitly commanded not to alter God’s Law. Deuteronomy 4:2 warns, “You shall not add to the word which I am commanding you, nor take away from it, so that you may keep the commandments of the Lord your God which I am commanding you.” Similarly, Proverbs 30:6 cautions, “Do not add to His words, or He will rebuke you, and you will be proved a liar.” These warnings underscore the importance of preserving God’s Word as He delivered it.
Just as God’s commands to Israel were complete, His revelation through Christ and the apostles is also final. Humanity has no authority to modify what God has decreed. As 2 John 1:9 teaches, “Anyone who goes too far and does not remain in the teaching of Christ does not have God; the one who remains in the teaching has both the Father and the Son.”
God Added No More to His Revelation
The New Testament confirms that God’s revelation is complete. Paul writes in 1 Corinthians 13:9-10, “For we know in part and prophesy in part; but when the perfect comes, the partial will be done away.” This “perfect” refers to the completion of God’s revealed will through His Word. Once the inspired writers of the New Testament completed their work, no further revelation was necessary.
James 1:25 describes Scripture as “the perfect law, the law of freedom.” Likewise, Paul affirms in 2 Timothy 3:16-17, “All Scripture is inspired by God and beneficial for teaching, for rebuke, for correction, for training in righteousness; so that the man or woman of God may be fully capable, equipped for every good work.” These verses highlight the sufficiency of Scripture to guide Christians in all matters of faith and practice. No additional revelation or human tradition is needed.
God Added Nothing to the Gospel
From the days of the apostles, the gospel has remained unchanged. Paul states in Romans 1:16, “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.” The message preached by Peter in Acts 2 remains the same today: repent, be baptized for the forgiveness of sins, and receive the gift of the Holy Spirit (Acts 2:38).
Throughout history, some have attempted to add to the gospel by introducing human traditions or innovations, such as the “mourner’s bench” or “praying through” to salvation. However, these practices go beyond what Scripture teaches. Galatians 1:8 warns against altering the gospel: “But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!” The plan of salvation revealed in the New Testament is sufficient and must not be modified.
God Added No More Baptisms
The New Testament teaches that baptism is essential for salvation and that there is one baptism for all believers. Ephesians 4:5 states, “one Lord, one faith, one baptism.” This baptism, as practiced in the early church, was for the forgiveness of sins and a public declaration of faith in Christ. Acts 2:38 records Peter’s instruction: “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit.”
Some have attempted to add additional baptisms or reinterpret its purpose. However, Romans 6:3-4 clarifies the meaning of baptism: “Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? Therefore we have been buried with Him through baptism into death, so that, just as Christ was raised from the dead through the glory of the Father, so we too may walk in newness of life.” No further baptism is required beyond the one instituted by Christ and His apostles.
God Added Nothing to the Name “Christian”
The term “Christian” was first used in Antioch to describe followers of Christ (Acts 11:26). This name, given by divine authority, signifies belonging to Christ. Peter affirms its significance in 1 Peter 4:16: “But if anyone suffers as a Christian, he is not to be ashamed, but is to glorify God in this name.”
Unfortunately, some have sought to add additional names or designations to distinguish groups or individuals within the church. However, Scripture recognizes only the name “Christian” as the identifier for God’s people. Adding human titles or labels undermines the unity of the church and the authority of Christ.
God Added Nothing to Worship
Worship in the New Testament is simple and spiritual, designed to honor God according to His will. Jesus declared in John 4:24, “God is spirit, and those who worship Him must worship in spirit and truth.” The early church practiced worship through prayer, singing, teaching, the Lord’s Supper, and giving (Acts 2:42; Ephesians 5:19; 1 Corinthians 16:2).
Attempts to add unauthorized elements to worship, such as instrumental music or man-made rituals, go beyond what Scripture prescribes. Colossians 3:17 instructs, “Whatever you do in word or deed, do everything in the name of the Lord Jesus, giving thanks through Him to God the Father.” Worship must align with God’s revealed will, not human preferences.
God Added No “Society System” to the Church
The church, as established by Christ, is sufficient for carrying out God’s work. Jesus declared in Matthew 16:18, “Upon this rock I will build My church, and the gates of Hades will not overpower it.” The church is described as a divine institution, fully equipped to fulfill its mission of spreading the gospel and edifying believers.
Some have argued that additional organizations or societies are necessary to support the church’s work. However, such structures often reflect human wisdom rather than divine guidance. Paul warns against this in 1 Corinthians 3:11, “For no one can lay a foundation other than the one which is laid, which is Jesus Christ.” The church alone is God’s appointed means for accomplishing His purposes.
Conclusion: Trusting in the Completeness of God’s Word
Deuteronomy 5:22 reminds us that God’s Word is complete, and He “added nothing more.” This principle extends to every aspect of Christian life—revelation, the gospel, baptism, worship, and the church. Revelation 22:18-19 issues a solemn warning: “I testify to everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues that are written in this book; and if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book.”
Let us honor God by adhering to His perfect Word, resisting the temptation to add or subtract from His commands. The gospel, as revealed in the New Testament, is sufficient to save, guide, and equip us for every good work. Trust in the completeness of His Word, for it is a reflection of His divine wisdom and authority.
