Sometimes it’s helpful to not be so critical of everyone who has authority (fathers, bosses) — our Father in heaven is also not Santa Claus. He punishes sin and is in some ways the most strict Father you can have — this is love as well.
In other words, it’s a sign of maturity to not be so wimpy.
You've never been in a truly abusive relationship, I gather. It's a sign of maturity to be humble and grateful for your blessings and not take pride in them by lecturing others less fortunate.
