I may be able to speak the languages of human beings and even of angels, but if I have no love, my speech is no more than a noisy gong or a clanging bell.
Our friends, we must thank God at all times for you. It is right for us to do so, because your faith is growing so much and the love each of you has for the others is becoming greater.
Above all, my friends, do not use an oath when you make a promise. Do not swear by heaven or by earth or by anything else. Say only “Yes” when you mean yes, and “No” when you mean no, and then you will not come under God's judgment.
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.
