1 Peter 1:16
for it is written: 'Be holy, because I am holy' — the citation from Leviticus 11:44-45 establishes that the call to holiness originates in God's own being and nature. The imperative follows from the indicative: because God is holy (hayah qadosh), those who stand in covenant with God must embody holiness. This principle, originally given in the Levitical holiness code, now applies to Christian believers.
