God is Love, and that must be preached and taught. God is Mercy and that must be preached and taught. God is Grace, and that must be preached and taught. But God is also Justice, and that also must be preached and taught.

I know it's easy to preach and teach that God is Love, He is Mercy and He is Grace. But it is not easy or "productive" to preach and teach that God is Justice. The Churches where God's Justice is preached and taught are empty. People don't want to hear about it. God tells us about Heaven and Hell, but most people want to hear about Heaven but nothing about Hell.

Yet, either He is everything or He is nothing. You can't slice God in smaller pieces, keep what you like and discard what you don't.
