I think in v2 is telling us to be a sacrifice to God. Just as Jesus did on the cross.
I try to keep from doing things listed in v4 but sometimes it's difficult. I think rude joking is what makes me mad the most.
We need to live our life not doing the things listed in this book. We can't get to the kingdom of heaven if we do these things . they are sinful God and sin don't mix.
Think of it like this. The husband is the leader or head. Wives need to submit to their husbands and listen to what they say. But the husband must be a good leader and make fair decisions. They need to become one flesh.
