What does the Bible say about the nature of our life?

The Scriptures often describe life in terms of days, with verses emphasizing its brevity. For instance, Psalm 90:12 says, 'So teach us to number our days, that we may apply our hearts unto wisdom.' This reflects the understanding that our earthly existence is temporary and our days are appointed, as highlighted in Job 14:5, stating, 'Seeing his days are determined, the number of his months are with thee.' As believers, recognizing the temporal nature of life should lead us to a deeper reliance on God and hope in eternal life.
