Trials are sent to some so as to take away past sins, to others so as to eradicate sins now being committed, and to yet others so as to forestall sins which may be committed in the future. These are distinct from the trials that arise in order to test men in the way Job was tested.
Be not forgetful to entertain strangers: for thereby some have entertained angels unawares. (Heb. 13:2) Accepting the task of hospitality, the patriarch [Abraham] used to sit at the entrance to his tent (cf. Gen. 18:1), inviting all who passed by, and his table was laden for all comers including the impious and barbarians, without distinction. Hence he was found worthy of that wonderful banquet when he received angels and the Master of all as guests. We too, then, should actively and eagerly cultivate hospitality, so that we may receive not only angels, but also God Himself. 'For inasmuch,' says the Lord, 'as you have done it to one of the least of these My brethren, you have done it unto Me' (Matt. 25:40). It is good to be generous to all, especially to those who cannot repay you.
When Abba Agathon went down to the city to sell some of his baskets and to procure a little bread, he found near the market place an old, poor cripple. 'For the love of God, Abba,' the cripple began to plead on seeing the Saint, 'don't you, too, leave this poor wretch unaided. Bring me near to you.' Abba Agathon picked the man up and sat him next to him in the place where he had set up his baskets to sell them. 'How much money did you make, Abba?' the cripple would ask each time that the Elder sold a basket. 'Such and such,' the Elder would tell him. 'That's good enough,' the cripple finally said. 'Won't you buy me a little pie, Abba? That would be good of you, since I have not eaten since last evening.' 'With pleasure,' the Saint told him, immediately fulfilling the cripple's request. Shortly thereafter, the cripple requested some fruit. And then some sweet. Thus, for each basket that was sold, the Saint spent the proceeds, until, thanks to his patronage, all of the baskets and money were gone, without his having kept even two pennies for himself. More importantly, he did this all with great eagerness, even though he knew that he would thus go perhaps two weeks without any bread for himself. Since he had sold his last basket, the Saint got ready to leave the marketplace. 'So you're going?' the cripple asked him. 'Yes, I have completed all of my work.' 'Uh, do me the favor of taking me as far as the crossroads, and you can leave for the desert from there,' the strange old man again pleadingly said. The good Agathon took the cripple on his back and carried him to the place where he wanted to go, though with great difficulty, since he was exhausted from his day's work. As soon as he reached the crossroads and started to put down his living burden, he heard a sweet voice say to him: 'May you be blessed, Agathon, by God, both on earth and in Heaven.' The Saint raised up his eyes to see who it was who had spoken with him. The would-be old man had completely disappeared, since he was an Angel sent by God to test the Saint's love.
I wish I could persuade spiritual persons that the way of perfection does not consist in many devices, nor in much cogitation, but in denying themselves completely and yielding themselves to suffer everything for the love of Christ. And if there is failure in this exercise, all other methods of walking in the spiritual way are merely a beating about the bush, and profitless trifling, although a person should have very high contemplation and communication with God.
Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: 'Stop, brother! I fall into graver sins every day, so how can I criticize him?' In this way you will achieve two things: you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. 'Judge not, and ye shall not be judged,' (Luke 6:37).
If your heart has been softened either by repentance before God or by learning the boundless love of God towards you, do not be proud with those whose hearts are still hard. Remember how long your heart was hard and incorrigible. Seven brothers were ill in one hospital. One recovered from his illness and got up and rushed to serve his other brothers with brotherly love, to speed their recovery. Be like this brother. Consider all men to be your brothers, and sick brothers at that. And if you come to feel that God has given you better health than others, know that it is given through mercy, so in health you may serve your frailer brothers.
In answer to your question as to what constitutes a happy life, whether splendor, fame and wealth, or a quiet, peaceful, family life, I will say that I agree with the latter, but will add the following: A life lived in humility and with an irreproachable conscience brings peace, tranquility, and true happiness. But wealth, honor, glory and exalted position often serve as the cause of a multitude of sins, and such happiness is not one on which to rely.
I must tell you that annoying incidents are unavoidable in this life. Those who are experienced in the spiritual life say that such incidents can even bring profit to the soul. Through annoying incidents we come to recognize that we are impatient - and if we are impatient, that means we are proud. And this awareness should dispose us to self-reproach and repentance, and to asking mercy from the Lord in prayer. But without annoying incidents a man is inclined to conceit.
Look at all the earth supplies in summer and in autumn! Every Christian, especially the priest, ought to imitate God's bountifulness. Let your table be open to everybody, like the table of the Lord. The avaricious is God's enemy.
