Proverbs 14:26 Whoever fears the Lord has a secure fortress, and for their children it will be a refuge.
As a parent myself I always have the thought of my children's safety going through my mind even though they are grown ups themselves nowadays.
Having a fortress you can withdraw to in order to be protected from adversities is always a good thing.
God is our fortress and He will keep us safe; what better option to have than the most secure fortress in the world!
