Ephesians 4:31

If we are to attain to the kingdom of Heaven, it is not enough to abandon wickedness, but there must be abundant practice of that which is good also. To be delivered indeed from hell we must abstain from wickedness; but to attain to the kingdom we must cleave fast to virtue.

The blessed Paul also, in leading us away from sin, leads us on to virtue. For where, tell me, is the advantage of all the thorns being cut out, if the good seeds be not sown? For our labor, remaining unfinished, will come round and end in the same mischief. And therefore Paul also, in his deep and affectionate anxiety for us, does not let his admonitions stop at eradicating and destroying evil tempers, but urges us at once to evidence the implanting of good ones. For having said, "Let all bitterness, and wrath, and clamor, and railing be put away from you, with all malice," he adds, "And be ye kind one to another, tender-hearted, forgiving each other." For all these are habits and dispositions. And our abandonment of the one thing is not sufficient to settle us in the habitual practice of the other, but there is need again of some fresh impulse, and of an effort not less than that made in our avoidance of evil dispositions, in order to our acquiring good ones.

He who is not our enemy, is not necessarily our friend; but there is an intermediate state, neither of enmity nor of friendship, which is perhaps that in which the greater part of mankind stand toward us. He that is not crying is not therefore necessarily also laughing, but there is a state between the two. And so, I say, is the case here. He that is not "bitter" is not necessarily "kind," neither is he that is not "wrathful" necessarily "tender-hearted"; but there is need of a distinct effort, in order to acquire this excellence.

And now look how the blessed Paul, according to the rules of the best husbandry, thoroughly cleans and works the land entrusted to him by the Husbandman. He has taken away the bad seeds; he now exhorts us to retain the good plants. "Be ye kind," saith he, for if, when the thorns are plucked up, the field remains idle, it will again bear unprofitable weeds. And therefore there is need to preoccupy its unoccupied and fallow state by the setting of good seeds and plants. He takes away "anger," he puts in "kindness"; he takes away "bitterness," he puts in "tender-heartedness"; he extirpates "malice" and "railing," he plants "forgiveness" in their stead.

As bees will never settle down in an unclean vessel, and this is the reason why those who are skilled in these matters sprinkle the spot with perfumes, and scented ointments, and sweet odors; and the wicker baskets also, in which they will have to settle as soon as they come out of the hives they sprinkle with fragrant wines, and all other sweets, that there may be no noisome smell to annoy them, and drive them away again, so in truth is it also with the Holy Spirit. Our soul is a sort of vessel or basket, capable of receiving the swarms of spiritual gifts; but if there shall be within it gall, and "bitterness, and wrath," the swarms will fly away. Hence this blessed and wise husbandman well and thoroughly cleanses our vessels, withholding neither knife nor any other instrument of iron, and invites us to this spiritual swarm; and as he gathers it, he cleanses us with prayers, and labors, and all the rest. Let us then distinctly understand what this bitterness is. Take, for example, the hollow-hearted man, the crafty, the man who is on the watch to do mischief, the man of evil suspicion. From him then "wrath" and "anger" are ever produced; for it is not possible for a soul like this to be in tranquillity, but the very root of "anger" and "wrath" is "bitterness." The man of this character is both sullen, and never unbends his soul; he is always moody, always gloomy. For as I was saying, they themselves are the first to reap the fruit of their own evil ways.
