For he shall not much remember the days of his life; because God answereth him in the joy of his heart. Ecclesiastes 5:20 (KJV)
The ISV reads “For he will not brood much over the days of his life, since God will keep him occupied with the joys of his heart.” Bartholmew directly quotes Lohfink here, “(this) implies that the ecstasy of the good is given within the psychic phenomenon of joy itself insofar as this is also a divine answer, something like revelation. In joy, then, the conclusion of right thinking namely the perfection and the eternity of divine action within all events is directly communicated as revelation.” (194) This is such a wholesome conclusion to the pursuit of labour and freedom, and it is such a fitting reward for the godly – to find joy in God. Adding to this, Seow notes – that the joy intended in these words are not future tense, but it is in the present tense. He writes, “the emphasis is not on the future, but on the possibility of enjoyment in the present.” (231)
