What the Bible says about Discouragement and Wandering Mind Connected
(From Forerunner Commentary)
In places within a culture where godliness must prevail so that people can live a truly good quality of life, Solomon instead found the grave impact of evil.
It is as if he has opened a door back to the harsh realities of this evil world, in which God has consigned us to live to prepare for His Kingdom. Living in this world while maintaining an “over the sun” way of life can be discouraging and difficult because its ever-present evil influences surround us, attempting to lure us into compromising with God's ways.
Overall, however, Ecclesiastes 3 is a strong, positive reminder of God's great gifting of us. In the face of everyday realities, though, we sometimes manage to forget to be thankful for that, allowing dangerous thoughts to arise that could motivate us back toward the world. Thus, Ecclesiastes 3:22 urges us to be content, exhorting us not to allow ourselves to be drawn into vanities, the often-attractive realities that the world holds out to us as invitations to rejoin it. Discouragement and a wandering mind go hand in hand.
