In this work, Antonio Montes Orozco explains how to mature our Faith to levels that give us peace to live, discovering the advantages of being with Jesus. These advantages entail: • Knowing that we will be saved. • Knowing that the decisions we make will be the right ones. • Receiving some miracles. • Having economic solvency. • Getting rid of some diseases. • Giving meaning to our life. • Being able to help those around us. • Having the necessary knowledge to understand that this is real and perfectly demonstrable. • In short, introducing ourselves on a path of continuous improvement toward Sanctity, and find Peacefulness. All this synthesized, reasoned and explained with examples, dialogues and summaries, especially for people with little time and who need to deepen quickly into Faith, so they begin to benefit as soon as possible. This is also indicated for people who have lived a long time in atheism or agnosticism, and find themselves in a difficult situation in life, almost bordering on despair.
