Go, eat your bread with joy, and drink your wine with a merry heart, for God has already approved what you do. Eccl. 9:7
I take Qohelet [the author of Ecclesiastes] to be saying that before we achieve what we want in our work (if we ever do), God is already smiling on us. God is pleased with us irrespective of what we do or do not accomplish. To use a somewhat different framework, God is pleased with our lives irrespective of our works. God simply smiles and gives us these gifts. That is the value of our work: the status as gifts according to grace, not visible results we can give back to God. (Eric Ortlund)
