Do you follow literally in everything in Leviticus?
I have never met anyone in my life who does, but I have heard many people quote select verses that reinforce their worldview.
By the way, most Christians believe Jesus superseded the code of Leviticus.
So now Christians are free to break the moral laws of the Old Testament ? That contradicts Jesus’ teaching:
Matthew 5:17 “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.”
The Old Testament law contains both ceremonial law and moral law as well as prophecy and the special revelation of God’s commands to the ancient Israelites in specific situations, i.e., go destroy a city, etc., which are specific commands that applied to those specific situations.
Jesus perfectly fulfilled the OT moral law by living a sinless life, living perfectly according to the OT moral law.
Jesus fufilled the OT ceremonial law as it foreshadowed his coming, ministry, death and resurrection.
Jesus fulfilled the prophets, of course, by being the prophesied Messiah.
God is unchanging - the Bible consistently teaches this.
God’s moral laws are also unchanging, and the Bible also consistently teaches this as well.
For example, murder is against God’s Law - it always was and always will be.
