The First Law of God in the Decalogue

The first law of God, as revealed in Scripture, is to love and worship Him alone, as stated in Exodus 20:3, "You shall have no other gods before Me." This commandment establishes the fundamental principle of the Christian faith, emphasizing the exclusive worship and devotion to the one true God. Paul writes in Romans 8:28 that all things work together for the good of those who love God, highlighting the importance of this commandment in the life of a believer. The first law of God addresses the heart's tendency to idolatry and serves as a reminder of humanity's inherent sinfulness and need for redemption through Christ.

This truth matters because it underscores the sovereignty of God and humanity's created purpose to glorify and enjoy Him. In Reformed theology, this commandment is seen as a reflection of God's holiness and His righteous standard for humanity. A common misconception is that this commandment is merely a moral guideline, but in reality, it is a reflection of God's character and a call to worship Him alone. The gospel connection is clear, as Jesus Christ is the ultimate fulfillment of this commandment, and through faith in Him, believers are enabled to love and worship God with their whole heart.

The pastoral perspective on this truth is one of humility and conviction, recognizing that the human heart is prone to idolatry and that only through the power of the gospel can believers be transformed to worship God alone. As believers, they are called to examine their hearts and lives, ensuring that they are giving God the exclusive worship and devotion that He deserves, and that they are living in accordance with His will, as revealed in Scripture, such as in Exodus 20:3, which serves as a foundational principle for the Christian life.
