But love your enemies, and do good, and lend, expecting nothing in return; and your reward will be great, and you will be sons of the Most High; for He Himself is kind to ungrateful and evil men. Be merciful, just as your Father is merciful. (Luke 6:35,36 NASB)
Give, and it will be given to you. They will pour into your lap a good measure—pressed down, shaken together, and running over. For by your standard of measure it will be measured to you in return.” (Luke 6:38 NASB)
I’ve said it a lot in this blog, Americans love their “return on investment”. We most often express it in the question, “What’s in it for me?” But this isn’t unique to American culture, I believe it’s easy to find in any human culture, past or present. The values may be different, but the question or interest in what’s valuable as a reward remains. It’s fundamental or foundational in human beings.
