Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.
Above all, love each other deeply, because love covers over a multitude of sins.
In the new life in Christ, there is nothing more revolutionary than the love which accompanies it. One is overcome with that love at the beginning, what is called “the love you had at first” (Revelation 2). Of course it has to be paired with truth; scripture does put “truth and love” together (2 John). One has to grow and mature in that love along with others, into the image of Christ.
Slights and attitudes that are wrong, of course showing up in one way or another in actions, do happen among believers. And when we think we’ve been the victim of such, we can isolate ourselves in hurt. Instead, somehow we need to love, and let go of that hurt. In doing so, we’re casting a real burden on the Lord, one might say. For sure, we’re obeying God’s word, which tells us who are in Jesus to keep loving each other deeply, since love covers over a multitude of sins.
If something is serious enough that we need to go to the person who perhaps sinned against us, we’ll have the discernment to realize such is the case. Even then, we go in much love, ready to listen and always to put the best construction on things. By and large, the passage above surely refers to those times when we simply let a small matter among a multitude of other small matters go. That can result not only in forgiving the offender, but in helping them change in accordance with God’s faithful working in their lives in Jesus.
At times we might be at the short end of the equation, so that we need grace extended as well. Though we ought to be sensitive to where we might have hurt someone in a way that was either unnecessary, unhelpful, or downright sinful.
There is nothing more basic in our lives in Jesus than this love, this overcoming love, which can help others into the same grace of God in Jesus, in which we stand, and out of which we live.
