Leviticus 3 is about the peace offering to God. Why does man need to come to God with a peace offering? Why are we called to be ministers of reconciliation? How is man at war with God that there needs to be peace talks?
Here’s what the Bible says.
Do you not know that friendship with the world is hostility toward God? Therefore, whoever wishes to be a friend of the world makes himself an enemy of God. (James 4:4)
This verse doesn’t leave any middle ground; you’re friends of the world or friends of God. Those are the only options. If we want to be friends with the world, then we are choosing to make ourselves an enemy of God.
Those choosing to be friends with God are going to find themselves an enemy of the world. They will hate the sin of the world and the world will hate the righteousness in them.
Here’s another verse that shows the distinction.
For the mind that is set on the flesh is hostile to God, for it does not submit to God’s law; indeed, it cannot. (Romans 8:7)
If you want to please God, then your mind has to be set on the Spirit. It is impossible for the mind set on flesh to please God.
Worldly people can try to be good. They can be activists and help others. They can have moral standards they live by, but it’s never going to be pleasing to God because they cannot submit to Him. They are submitting to their own ideals.
So, what can we do? We can be reconciled to God through Jesus. Colossians 1 talks about it.
And you, who once were alienated and hostile in mind, doing evil deeds, he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him, if indeed you continue in the faith, stable and steadfast, not shifting from the hope of the gospel that you heard… (Col 1:21-23)
It says that if we continue in the faith, Jesus will present us to the Father blameless, above reproach. There will be nothing to say against us. By the blood of Jesus, we go from hostiles to friends, from sinner to saint, from alien to child.
