I am tolerably ignorant about Judaism, and much of what I do know about it seems hard to swallow, because it is so grounded in legalism, and adherence to rituals.
Only Christ can free us from the prison of legalism, and then only if we are willing to be freed.
Legalism says God will love us if we change. The gospel says God will change us because He loves us.
Legalism breeds a sense of entitlement that turns us into complainers.
