You can show your love to others by not wishing that they should be better Christians.

Let us also love our neighbors as ourselves. Let us have charity and humility. Let us give alms because these cleanse our souls from the stains of sin. Men lose all the material things they leave behind them in this world, but they carry with them the reward of their charity and the alms they give. For these they will receive from the Lord the reward and recompense they deserve.

And in any preaching you do, admonish the people concerning repentance, and that nobody can be saved except he who receives the most holy Body and Blood of our Lord. And when It is sacrificed on the altar by the priest or borne anywhere, let all the people on bended knees render praise, glory and honor to the True and Living Lord God.

What you are looking for is what is looking.

Dear God, please reveal to us your sublime beauty, that is everywhere, everywhere, everywhere, so that we will never again feel frightened.

It is not fitting, when one is in God's service, to have a gloomy face or a chilling look.

Preach always. Use words if necessary.
