Our Lord's repeated calls for us to be charitable at all times, and especially in his New Commandment must stimulate us to follow His lead by finding concrete ways of being of help to others, such as by making those at our side happy, realizing that we can never be too extravagant in the practice of this virtue. Most of the time the practice of charity will consist in little details, something as simple as a smile, a word of encouragement, a kind gesture ... In the eyes of God all of this is very pleasing and draws us closer to Him. In our prayer today we should also consider areas where we can easily lack charity if we are not careful: rash judgements, negative criticism, neglect of others due to self-centeredness, forgetfulness ... The Christian way of conduct is not the way of an eye for an eye and a tooth for a tooth, but to do good always, even though occasionally such an attitude will not result in any human gain in this world - but at least we will have enriched our hearts.
