The Fear of God is the beginning of Wisdom so I think it is a good idea to think about God's wrath as much as possible. Work out your salvation in Fear and trembling.
"A Christian ending to our life, painless, blameless, peaceful, and a good defense before the dread judgement seat of Christ, let us ask of the Lord."
I think we keep God's wrath and judgment in our minds. Yet, we also must remember His grace:
"Help us, save us, have mercy upon us, and keep us, O God, by Thy grace."
