Walking the Narrow Path

What will it take for the followers of Christ to walk on the narrow path and pass through the tight gate that leads to the kingdom of God in this fallen world and with our fallen human nature inclined to God’s disobedience and sin?
Is there any hope to fulfill this goal? To accept fully the invitation of Jesus Christ to walk the narrow path to follow him from our stagnation to the liberation of His company in Paradise?
To try to answer these questions, the author presents a scenario that all disciples of Jesus will encounter if they attempt this path, and provides some advises on how to face the difficulties that surely will appear to those that will engage in this spiritual battle.
