1 Peter 3:8-18
"Finally, all of you, have unity of spirit, sympathy, love for one another, a tender heart, and a humble mind. Do not repay evil for evil or abuse for abuse; but, on the contrary, repay with a blessing. It is for this that you were called—that you might inherit a blessing."
We are so used to the idea that you get what you give, that we should receive the types of actions that we ourselves invest. Yet the message of the New Testament continually turns this understanding upside down.
We are taught to repay abuse with blessing. We are taught that regardless of what someone does, we should forgive. Why? We're told that we should do this to mirror what God has done for us. Would we want God to treat us how we treat one another? Knowing the mistakes we make and the abuses of our lives, I doubt that any of us do.
And so we are taught a different rule. We are taught that regardless of how we might be wronged, we are to show love nonetheless. That is a Lenten discipline worth pursuing, and one that takes practice.
