God is less impressed with those who have a tremendous amount of theological grace than those who display grace in their lives. It's one thing to say that God has abundant grace, but unless we show it ourselves, no one will believe it.
For this reason, severe judgment will be put on people if they reject practical mercy and grace and forgiveness in their lives. God reserves hell for those who put other people through hell now.
"If you forgive others for their transgressions, your heavenly Father will also forgive you. But if you do not forgive others, then your Father will not forgive your transgressions."
"For judgment will be merciless to one who has shown no mercy; mercy triumphs over judgment."
