READ GALATIANS 4:21-31
And just as Ishmael the slave son persecuted Isaac the son of promise, so you and I who are free will be persecuted by those who love legalism. Those who love the things of the Old Covenant will persecute those who are free in the New Covenant, trying to get them into the same bondage. Legalism is nasty. But Old Covenant legalism will never inherit what Jesus died for. The promises of God are for you and I who are free.
