How do we know that God protects His people from judgment?

Throughout Scripture, particularly evident in the plagues of Egypt, God demonstrates His distinguishing grace by sparing the Israelites while pouring out judgment on the Egyptians. For example, in Exodus 8:22-23, God declares that He will put a division between His people and the Egyptians, ensuring their safety during calamities. This illustrates the deeper spiritual truth that all believers, through their union with Christ, are protected from God's wrath because Christ has borne it on their behalf, signifying that those in Christ will always be secure from eternal judgment.
