Psalm 90:9-12

"For all our days pass away under your wrath;
   we bring our years to an end like a sigh.
The years of our life are seventy,
   or even by reason of strength eighty;
yet their span is but toil and trouble;
   they are soon gone, and we fly away.
Who considers the power of your anger,
   and your wrath according to the fear of you?
So teach us to number our days
   that we may get a heart of wisdom. "
   - Psalm 90:9-12 (italics added)

Life is unthinkably short. Our several decades on this planet are nothing compared to how God sees time (cf. Psalm 90:4). Cancer takes us, accidents take us, war takes us, and ultimately the decay of sin on our physical bodies takes us from this world that is passing away.

The man who follows the admonitions in Ps. 90:11 and Ps. 90:12 is wise indeed.
Do we consider the power of God's anger? Do we consider his wrath as we fear God? His anger and wrath are indeed awesome. Thanks be to God that those who have the Son will not see a drop of the wrath of God, save when we remember how all his wrath was indeed poured out on his Son for our sin.

Will we consider the cross of Jesus? Consider how Jesus Christ took the full cup of wrath of his Father on our behalf, Christian. Consider the fury laid upon the sinless Son of Man. Consider the sheer power of God's anger as Jesus bore sin that was not his. Consider the wrath poured out on the Christ physically. See his body torn and beaten beyond recognition. Consider this.

Our bodies are indeed passing away and wise is the man who thinks not that this body is immortal. Yes, there will be new bodies for all men, and they are to be given to an eternity of pleasure or wrath. Wise is the man who does not squander his unthinkably short time on this planet for indeed, we are not promised tomorrow (James 4:14).
