There is a class of people who boast of their honesty and frankness because they "just say what they think," flinging out the words right and left as they come, no matter where they strike or whom they wound. Call it not honesty, this boasted frankness; call it rather miserable impertinence, reckless cruelty. We have no right to say what we think unless we think lovingly and sweetly. We certainly have no right to unlade our jealousies, envies, bad humours, and miserable spites upon our neighbour's heart. If we must be ugly-tempered, we should at least keep the ugliness locked up in our own breast, and not let it out to mar other people's happiness. Or, if we must speak out the wretched feelings, let us go into our own room and lock the door and close the windows, that no ears but our own shall hear the hateful words.

It is in the intention of the words you speak however. Best friends are frank to each other but only for the good of the other. But if you meant it for the good of a friend or loved one, again say it sweetly and loving so that they are inspired to change and motivated to be a better Christian and not develop any sense of unhappiness within them.

Also, do not say things that may stumble others, Christians and non-Christians alike. "31So whether you eat or drink or whatever you do, do it all for the glory of God. 32Do not cause anyone to stumble, whether Jews, Greeks or the church of God— 33even as I try to please everybody in every way. For I am not seeking my own good but the good of many, so that they may be saved."
