Jon van Jon in Les Miserables said “To love someone is to see the face of God”. Someone had shown him love and kindness in his life and he went on to show mercy and kindness to many others.
Jesus said Blessed are the merciful for they shall obtain mercy. It is good in one’s young life to learn to be kind and merciful to others. This way of life is often learned in growing up in family. The older children helping the younger children. Learning to give and share. Learning to forgive. Learning to be patient with one another. Learning to be supportive and respectful to elderly parents. It is the way of love.
These attributes are easily carried into adulthood. It will be easy then to reach out to someone in need: the baby, the foreigner, the widow, the orphan, the sick, the lonely and the elderly.
Jesus guarantees that when one lives a life of thinking of others that person will always get help when he is in trouble.
So young people learn to be kind when you are young. When you are older and faced with trouble your kindness will be remembered by God.
