to your godliness add Christian affection; and to your Christian affection add love.
Keep on loving one another as Christians.
Love one another warmly as Christians, and be eager to show respect for one another.
May the Lord make your love for one another and for all people grow more and more and become as great as our love for you.
So then, as often as we have the chance, we should do good to everyone, and especially to those who belong to our family in the faith.
The command that Christ has given us is this: whoever loves God must love others also.
This is how we know what love is: Christ gave his life for us. We too, then, ought to give our lives for others!
We know that we have left death and come over into life; we know it because we love others. Those who do not love are still under the power of death.
Respect everyone, love other believers, honor God, and respect the Emperor.
Now that by your obedience to the truth you have purified yourselves and have come to have a sincere love for other believers, love one another earnestly with all your heart.
And to all these qualities add love, which binds all things together in perfect unity.
To conclude: you must all have the same attitude and the same feelings; love one another, and be kind and humble with one another.
See that no one pays back wrong for wrong, but at all times make it your aim to do good to one another and to all people.
