We have to serve those amongst whom the Lord has placed us, learning in this matter from Our Lady.
The greatest among you must be your servant,  says the Lord. Thus we have to leave our egoism to one side and discover in ourselves those signs of charity which make others happy. If we do not make the daily effort to forget ourselves, we will pass by those who are near us over and over again without realising that they could do with a word of encouragement, that they need their work to be appreciated, and lack perhaps only a word of encouragement from us for them to be better.
Egoism blinds; it narrows our horizons when we look at others; humility constantly opens up a way to charity in practical details and suggests specific ways of serving. This joyful spirit, of openness to the others, and the spirit of availability, is capable of transforming any environment. Charity warms up as water in a rock fissure. Love draws out love,  says St Teresa; and St John of the Cross advises: where there is no love, put love, and you will draw out love. 
But we were gentle among you, like a nurse taking care of her children. So, being affectionately desirous of you, we were ready to share with you not only the Gospel of God but also our own selves,  exclaims St Paul to the Christians of Thessalonica. If we imitate him, our actions will bear similar fruit.
We have to practise this spirit of Christ with those nearest to us, within the family: The husband ought not to seek only his own interests, but also those of his wife; and she, those of her husband. Parents should look after the interests of their children, and these in turn look after the interests of their parents. The family is the only community in which man ‘is loved for himself’, for what he ‘is’ and not for what he ‘has’ ... Respect for this fundamental norm explains, as the Apostle himself teaches, why nothing should be done out of a spirit of rivalry or for vainglory, but rather through humility, because of love. And this love, which is opened up to others, makes members of the family true servants of ‘the domestic church’, where all desire the good and the happiness of each one; where each and every one gives life to this love with an urgent search for that good and that happiness. 
If you act in this way, you will not be inclined to see, as so often happens, the speck in your brother’s eye without seeing the log in your own.  The tiniest imperfections of others are magnified in our perspective and our own graver faults tend to be minimised and all too easily justified.
Humility, on the other hand, makes us recognise our own weaknesses and defects. We are then in a position to be understanding towards the shortcomings of other people and to be able to extend to them a helping hand. We are then also able to love them and to accept them with whatever defects they may have.
The Blessed Virgin, handmaid of the Lord, will teach us to understand that to serve others is one of the ways of finding joy in this life and one of the shortest routes to Jesus.
