Courtesy is one of the graces of the Spirit. It is an attribute of Heaven. The angels never fly into a passion, never are envious or selfish. No harsh or unkind words escape their lips. If we are to be the companions of angels, we too must be refined and courteous.
The truth of God is designed to elevate the receiver, to refine his taste and sanctify his judgment. No man can be a Christian without having the spirit of Christ; and if he has the spirit of Christ, it will be manifested in a refined, courteous disposition. His character will be holy, his manners comely, his words without guile. He will cherish the love that is not easily provoked, that suffers long and is kind, that hopes all things and endures all things....
Those who profess to be followers of Christ and are at the same time rough, unkind, and uncourteous in words and deportment have not learned of Jesus.... The conduct of some professing Christians is so lacking in kindness and courtesy that their good is evil spoken of. Their sincerity may not be doubted, their uprightness may not be questioned; but sincerity and uprightness will not atone for a lack of kindness and courtesy. The Christian is to be sympathetic as well as true, pitiful and courteous as well as upright and honest....
True courtesy blended with truth and justice makes the life not only useful but beautiful and fragrant. Kind words, pleasant looks, a cheerful countenance, throw a charm about the Christian that makes his influence almost irresistible. In forgetfulness of self, in the light and peace and happiness that he is constantly bestowing on others, he finds true joy.
Let us be self-forgetful, ever on the watch to cheer others, to lighten their burdens by acts of tender kindness and deeds of unselfish love. Leave unspoken that unkind word; let that selfish disregard of the happiness of others give place to loving sympathy. These thoughtful courtesies, beginning in the home and extending far beyond the home circle, go far to make up the sum of life’s happiness, and the neglect of them constitutes no small share of life’s misery.

The reason why so many are left to themselves in places of temptation is that they do not set the Lord always before them. Pr 213
