Psalms 78:39
For he remembered that they were but flesh; a wind that passeth away, and cometh not again.
Psalms 78:39 (KJV)
Context
Psalm 78 is a historical psalm written by Asaph. It retells the story of Israel from Egypt to the time of David, showing how the people often rebelled against God. Verse 39 comes right after God forgave their sins and turned away His anger. This verse explains why God showed mercy: He remembered that they were only human.
Meaning
The word “flesh” here means more than skin and bones. It points to human weakness, frailty, and mortality. People are poor, weak creatures who cannot bear the full weight of God’s wrath. If God punished them completely, they would be crushed and would perish. The verse also says that humans are “a wind that passeth away, and cometh not again.” Life is like a breath of air or a breeze that drifts by and never returns. It is brief and cannot be recovered. This frailty also means that people are naturally sinful and prone to evil, easily drawn into sin. Yet God’s response is not to destroy them but to remember their condition.
Biblical connections
This teaching connects with Psalm 103:14, where God remembers that we are dust. In both places, God’s compassion is rooted in His knowledge of what humans are made of. He does not deal with us according to our sins because He knows our frailty. This is not weakness in God; it is His loving character. The same truth appears throughout Scripture: God’s mercy is tempered by His understanding of our mortality.
Application
Knowing that life is short should lead us to humility. We are not strong or self-sufficient. We depend on God for every breath. This truth also gives us comfort. When we fail, God does not crush us. He remembers our weakness and treats us with patience. We can come to Him honestly, without pretending to be stronger than we are. Because our days are few, we should not waste them in pride or self-reliance.
Reflection
God’s mercy is not careless. It is based on His true knowledge of our condition. He sees that we are but flesh, a passing wind. Yet He still loves us and calls us to trust Him. Because our time on earth is short, we should seek Him now and build our lives on His eternal faithfulness.
