Why does God command us to be holy? It's not an arbitrary rule. This verse connects our calling directly to His very nature.
God's Character as the Standard
The command to 'be holy' isn't just about following a set of rules. Peter is drawing from the Old Testament, specifically Leviticus 11:44-45 and 19:2, where God Himself declares His holiness and then calls His people to be like Him.
It's About Relationship
Holiness, in this context, means to be set apart, distinct, and pure – reflecting the character of God. It's His unchanging, perfect nature that serves as the ultimate model. Because God is holy, His people are called to be holy, not to earn His favor, but because they belong to Him.
