First of all, I want to say I love that God raised up a woman to lead the people of Israel. For me, it says that God values women and their gifts and talents.
Second, I think this passage reminds us that culturally these people are not us.
Times change. Generally speaking we don't sing praise songs to God about smashed heads.
I'm glad culture shifts.
I'm glad women have value in our culture.
I'm glad we believe in equality for people of every color.
Even though people of faith didn't always follow this value, equality is God's idea.
The Message version of Galatians 3:28 says it this way:
In Christ's family, there can be no division into Jew and non-Jew, slave and free, male and female. Among us you are all equal.
