Ecclesiastes 5:18-20 New International Version (NIV)
18 This is what I have observed to be good: that it is appropriate for a person to eat, to drink and to find satisfaction in their toilsome laborunder the sun during the few days of life God has given them—for this is their lot. 19 Moreover, when God gives someone wealth and possessions,and the ability to enjoy them, to accept their lot and be happy in their toil—this is a gift of God. 20 They seldom reflect on the days of their life, because God keeps them occupied with gladness of heart.
Matthew 5:13-16 New International Version (NIV)
Salt and Light
13 “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.
14 “You are the light of the world. A town built on a hill cannot be hidden.15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. 16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
