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

In the Bible, the temporality of human existence is underscored repeatedly, reminding us that our current struggles and stages of life are only for a little while. Jesus himself affirms in John 16:16-33 that pain and heartache will last only a short time for His disciples. This concept is further elaborated by the Apostle Paul in 2 Corinthians 4:17, where he refers to our afflictions as light and momentary compared to the eternal glory that awaits us. Such teachings encourage believers to maintain a heavenly perspective, recognizing that even our trials are working for us a greater purpose beyond the fleeting nature of this life.
