Pro 19:15 Slothfulness casteth into a deep sleep; and an idle soul shall suffer hunger.Remember the old film short that showed a lazy grasshopper, lolling about in the summer, while the ants busily laid up stores for the winter? Later in the short, you saw the grasshopper shivering in the cold, knocking on the ant's door, and asking for something to eat! Somehow I think that even a busy king like Solomon probably remembered being a child and watching those busy ants. This (verse 15) is one of several verses where he warns us about slothfulness.
Pro 19:16 He that keepeth the commandment keepeth his own soul; but he that despiseth his ways shall die.
Pro 19:17 He that hath pity upon the poor lendeth unto the LORD; and that which he hath given will he pay him again.
In verse 16, Solomon cautions us to keep the commandments, and not to "despise" our ways. The study Bible I have notes that in this verse, despise is a synonym for scorn. Perhaps he is also cautioning us to value the good ways, the right paths, and the commandments.
The last verse reminds me of my grandma: she was always doing nice things for others, and when I was really small, she began teaching me that I should "cast my bread upon the waters" . . . in today's language I guess this would be "what goes around comes around" or even "paying it forward."
This is indeed yet another way of phrasing this "law" or concept that can bring blessings. Many people embody this in their lives. They are generous to those less fortunate -- they are team players -- they don't seek credit, but are happy for all to be enriched.
There is definitely a time to sow, and a time to reap. Many people think that you can do both at the same time. However, you can't be sure when or from where you will reap --- but it will happen. More than likely, the same person to whom you give, will not be the person who will repay your kindness. But God takes what we sow, and multiplies it into abundance. So, cheerfully do all that's in your power to lift, to build, to serve and help others from morning until night. You never know when or how your blessings will return, but you know it's a promise from Him.
