Indeed, when we fail to live as children of God, we often behave in a destructive way towards our neighbours and other creatures – and ourselves as well – since we begin to think more or less consciously that we can use them as we will. Intemperance then takes the upper hand: we start to live a life that exceeds those limits imposed by our human condition and nature itself. We yield to those untrammelled desires that the Book of Wisdom sees as typical of the ungodly, those who act without thought for God or hope for the future (cf. 2:1-11). Unless we tend constantly towards Easter, towards the horizon of the Resurrection, the mentality expressed in the slogans “I want it all and I want it now!” and “Too much is never enough”, gains the upper hand.
The root of all evil, as we know, is sin, which from its first appearance has disrupted our communion with God, with others and with creation itself, to which we are linked in a particular way by our body. This rupture of communion with God likewise undermines our harmonious relationship with the environment in which we are called to live, so that the garden has become a wilderness (cf. Gen 3:17-18). Sin leads man to consider himself the god of creation, to see himself as its absolute master and to use it, not for the purpose willed by the Creator but for his own interests, to the detriment of other creatures.
Once God’s law, the law of love, is forsaken, then the law of the strong over the weak takes over. The sin that lurks in the human heart (cf. Mk 7:20-23) takes the shape of greed and unbridled pursuit of comfort, lack of concern for the good of others and even of oneself. It leads to the exploitation of creation, both persons and the environment, due to that insatiable covetousness which sees every desire as a right and sooner or later destroys all those in its grip….
All creation is called, with us, to go forth “from its bondage to decay and obtain the glorious liberty of the children of God” (Rom 8:21). Lent is a sacramental sign of this conversion. It invites Christians to embody the paschal mystery more deeply and concretely in their personal, family and social lives, above all by fasting, prayer and almsgiving.
Fasting, that is, learning to change our attitude towards others and all of creation, turning away from the temptation to “devour” everything to satisfy our voracity and being ready to suffer for love, which can fill the emptiness of our hearts. Prayer, which teaches us to abandon idolatry and the self-sufficiency of our ego, and to acknowledge our need of the Lord and his mercy. Almsgiving, whereby we escape from the insanity of hoarding everything for ourselves in the illusory belief that we can secure a future that does not belong to us. And thus to rediscover the joy of God’s plan for creation and for each of us, which is to love him, our brothers and sisters, and the entire world, and to find in this love our true happiness.
Dear brothers and sisters, the “lenten” period of forty days spent by the Son of God in the desert of creation had the goal of making it once more that garden of communion with God that it was before original sin (cf. Mk 1:12-13; Is 51:3). May our Lent this year be a journey along that same path, bringing the hope of Christ also to creation, so that it may be “set free from its bondage to decay and obtain the glorious liberty of the children of God” (Rom 8:21). Let us not allow this season of grace to pass in vain! Let us ask God to help us set out on a path of true conversion. Let us leave behind our selfishness and self-absorption, and turn to Jesus’ Pasch. Let us stand beside our brothers and sisters in need, sharing our spiritual and material goods with them. In this way, by concretely welcoming Christ’s victory over sin and death into our lives, we will also radiate its transforming power to all of creation.
