How does God reveal Himself in the Old Testament?

In the Old Testament, God's revelation comes in various forms, showing His holiness, justice, and power. For instance, Exodus 19 depicts God descending on Mount Sinai as a consuming fire, emphasizing His otherness and the seriousness of approaching Him. This stark image serves not only as a warning but also as a preparation for worship, illustrating that God is to be approached with understanding and awe. Malachi 3:6 reminds us that 'I am the Lord, I do not change,' reaffirming that God's character remains constant throughout Scripture. This revelation fosters a proper understanding of His nature, which is vital for understanding the grace offered in Christ in the New Testament. God’s consistent portrayal as holy motivates believers to approach Him with reverence and to comprehend the cost of our salvation.
