Every man to whom God hath given riches and wealth, and hath given him power to eat thereof, and to take his portion, and to rejoice in his labour; this is the gift of God. Ecclesiastes 5:19 (King James Version)
Let's take a moment and think a little about this verse. I don't think it is referring to "riches and wealth" as being very wealthy or having great riches. I believe it is referring to having enough for what you need and then perhaps some to share.
This being the case, we are given "power to eat thereof" - you know having our tummies full, having our needs met, and being able to do it in joy.
Also, we are able to "take his portion" as in we have what we need - for there is no other way to truly view your "portion" as anything other than what you need.
And then where do we get this "riches and wealth"? Why we get it from our labours and now we are able to "rejoice in our labours." It is wonderful to have the mental acuity, physical health and strength, and opportunity to actually WORK or LABOUR.
And then, finally, we can recognize that all this is a "gift of God." What a joy to know that God provides our labor, our portion, and the rejoicing we have in these.
