“He who observes the wind will not sow, and he who regards the clouds will not reap” (v4). While the proverbs teach us to plan ahead and listen to counsel, Ecclesiastes adds that pondering and analysis have their limits. Eventually, we must act, even in the face of imperfect knowledge and risk, because the time for harvesting is limited. Death comes to us all (only God knows when), so we must live fully, giving thanks for each day we have (ch 12).
Without knowing the future, we live today by faith. We can commit fully to whatever work we are called to do (11:6), leaving “the end of the matter” to God (12:13).
