The power of God is effective when a person asks for the help from God, acknowledging his own weakness and sinfulness. This is why humility and the striving towards God are the fundamental virtues of a Christian.
John of Shanghai and San FranciscoMore John of Shanghai and San Francisco quotes
Our Grief Over the death of our close ones would be inconsolable and boundless if the Lord had not given us eternal life. Our life would be meaningless if it ended with death. What benefit, then, would there be from virtue or good deeds? They would be right who say, "Let us eat and drink, for tomorrow we die!” But man was created for immortality....
John of Shanghai and San Francisco
Just as a basic concern is to be careful of anything that might be harmful to our physical health, so our spiritual concern should watch out for anything that might harm our spiritual life and the work of faith and salvation. Therefore, carefully and attentively assess your inner impulses: are they from God or from the spirit of evil?
John of Shanghai and San Francisco
Those forces that are preparing the appearance of Antichrist will have a leading significance in public life. Antichrist will be a man and not the devil incarnate. ... That man wants to be in place of Christ, to occupy His place and possess that which Christ ought to possess. He wants to possess the same attraction and authority over the whole world.
And he will receive that authority before his own destruction and that of the whole world. He will have a helper, a Magus, who, by the power of false miracles, will fulfill his will and kill those that do not recognize the authority of Antichrist.
