"Res ipsa loquitor", a Latin term used in a legal context, means "the thing speaks for itself" - which otherwise means, it needs no further explanation than what can be seen with the eyes or heard with the ears or proven with action.
Action speaks louder than words.
Simplicity & sublimity conveys the love of Christ. The touch of a hand to the dejected, the warm hug to the despaired, the cash aid to the financially burdened, a shelter to the homeless, a family to the orphan, love to the unwanted.
Action speaks louder than religion.
Islam talks of Allah, the compassionate one. But it was Jesus who went to the cross. Compassion literally means to suffer weight.
