To be a disciple of Jesus means that we can and must follow a way that is directly opposed to our own natural gravity, to the gravity of egoism, to the search for what is merely material and for the maximum pleasure that we confuse with happiness. Discipleship is a way through agitated, stormy waters that we can follow only if we are in the gravitational field of the love of Jesus Christ, if our gaze is fixed on him and therefore supported by the new gravity of grace that makes possible for us the way to truth and to God that we would have been unable to follow by our own efforts. That is why being a disciple of Jesus is more than concurrence with a definite program, more than sympathy and solidarity with a person whom we regard as a model. It is not just Jesus, a human being, that we follow; we follow the Son of the living God. We follow a divine way. Where does Jesus’ way lead us? It leads us to the Resurrection, to the right hand of the Father. It is this whole way that we mean when we speak of following Christ as his disciple. Only thus do we journey the whole way of our vocation; only thus do we really reach the goal of undivided and imperishable happiness. And only from this perspective do we understand why the Cross is also a part of our discipleship as followers of Christ (cf. Mk 8:24). There is no other way for us to come to the Resurrection, to the community of God. We must follow the whole way if we want to be servants and witnesses of Jesus Christ. And every single step is different depending on whether we intend to go the whole way or merely to carve out for ourselves a kind of human party program. We can come to Christ only if we have the courage to walk on the water and to entrust ourselves to his gravity, the gravity of grace.
