The story of the long journey carried out by the church through the centuries, the advancement of Christianity and the overcoming of so many obstacles so that it could reach the present moment of the Christian faith with its message of forgiveness and salvation for the lost, giving them the right to again to be accepted as children and heirs of his infinite mercy, is much greater and more complex than what has been described in this little work on the subject. However, for those who exhaustively seek knowledge about the gospel path so far, this short study will be useful to you to understand that God is infallible in his providence to keep his Word and promises alive in this world that is dominated by spiritual darkness and where justice seems to have been forgotten.
