St. John Chrysostom was know for his emphasis on 'practical' Christianity in the lives of all believers. Here is an excerpt from his Homily on Matthew 11...
And all these let us practise at home, with our own friends, with our wife, with our children. And, for the present, let us begin with the things that come first, and are easier; as for instance, with not swearing; and let us practise this one letter continually at home. For, in truth, there are many at home to hinder this our practice; sometimes a man's servant provoking him, sometimes his wife annoying and angering him, sometimes an indocile and disorderly child urges him on to threatening and swearing. If now at home, when thus continually galled, thou shouldest attain not to be tempted into swearing, thou wilt in the market-place also have power with ease to abide unconquered.
Yea, and in like sort, thou wilt attain to keep thyself from insulting any, by not insulting thy wife, nor thy servants, nor any one else among those in thy house. For a man's wife too not seldom, praising this or that person, or bemoaning herself, stirs him up to speak evil of that other. But do not thou let thyself be constrained to speak evil of him that is praised, but bear it all nobly. And if thou shouldest perceive thy servants praising other masters, be not perturbed, but stand nobly. Let thy home be a sort of lists, a place of exercise for virtue, that having trained thyself well there, thou mayest with entire skill encounter all abroad.
Do this with respect to vainglory also. For if thou train thyself not to be vainglorious in company of thy wife and thy servants, thou wilt not ever afterwards be easily caught by this passion with regard to any one else. For though this malady be in every case grievous and tyrannical, yet is it so especially when a woman is present. If we therefore in that instance put down its power, we shall easily master it in the other cases also. And with respect to the other passions too, let us do this self-same thing, exercising ourselves against them at home, and anointing ourselves every day.
And that our exercise may be easier, let us further enact a penalty for ourselves, upon our transgressing any of our purposes. And let the very penalty again be such as brings with it not loss, but reward,--such as procures some very great gain. And this is so, if we sentence ourselves to intenser fastings, and to sleeping often on the bare ground, and to other like austerity. For in this way will much profit come unto us from every quarter; we shall both live the sweet life of virtue here, and we shall attain unto the good things to come and be perpetually friends of God.
But in order that the same may not happen again,--that ye may not, having here admired what is said, go your way, and cast aside at random, wherever it may chance, the tablet of your mind, and so allow the devil to blot out these things;--let each one, on returning home, call his own wife, and tell her these things, and take her to help him; and from this day let him enter into that noble school of exercise, using for oil the supply of the Spirit. And though thou fall once, twice, many times in thy training, despair not, but stand again, and wrestle; and do not give up until thou hast bound on thee the glorious crown of triumph over the devil, and hast for the time to come stored up the riches of virtue in an inviolable treasure-house.
For if thou shouldest establish thyself in the habits of this noble self-restraint, then, not even when remiss, wilt thou be able to transgress any of the commandments, habit imitating the solidity of nature. Yea, as to sleep is easy, and to eat, and to drink, and to breathe, so also will the deeds of virtue be easy to us, and we shall reap to ourselves that pure pleasure, resting in a harbor without a wave, and enjoying continual calm, and with a great freight bringing our vessel into haven, in that City, on that day; and we shall attain unto the undecaying crowns, unto which may we all attain, by the grace and love towards man of our Lord Jesus Christ, to whom be all glory and might, now and always, and world without end. Amen.
