How Right Behavior Returns Right Behavior To Us
Luke 6
People want to be kind, because it's how God made us. But the sin-flesh keeps us down with excuses for us to keep submitting ourselves to it. So, when you do plain right all the time, the excuses are taken out of the way, and the other person (even a person who is usually embittered toward us like an enemy) is more free in your company to express the natural things that God created us all to keep delighting in.
It's not about tit-for-tat, it's about the natural working of God's Universe. That's what He's been teaching humanity in His Bible this whole time. And the same goes for the painful things that He's been teaching us, too. It's the way His Universe works, and it expresses His attributes, even so much that He called it "very good" when He created it.
The Worldlings' sin keeps them from believing Jesus' saving work and verbally confessing Jesus Master to be saved. That's why they remain His enemies and ours. Our sin confuses us, but God's goodness is more powerful! It works to keep the worst evil from overtaking the whole Earth all at once, and it works in us who are known by Him to produce better behavior in us, even when we allow our bodies to willfully sin - His righteousness is greater than our bodies!
And we are made very glad! And He is honored, glorified in the fact that we are still alive, even in the middle of all this death!
