When God gives any man wealth and possessions, and enables him to enjoy them, to accept his lot and be happy in his work - this is a gift from God. (v19)
When God enables us to enjoy our wealth and possession that is when the blessing can bless. Wealth is delightful when it is rooted in a attitude of stewardship and favour and joyful generosity. This is a gift from God.
When God enables us to accept our lot in life and our roving eyes settle on our current horizon with faith & gratitude of heart, this is a gift from God.
When God enables us to be happy in our labour and the dignity of work restored, this too is a gift from God.
When God gives these gifts, we will seldom reflect on the days of our life because God would have kept us occupied with joy in ours hearts.
