Following The Good

Rogamus vero vos, fratres, corripite inquietos, consolamini pusillanimes, opitulamini infirmis, patientes estote ad omnes. Videte ne quis malum pro malo alicui reddat: sed semper quod bonum est sectamini et in invicem, et in omnes. Semper gaudete in Domino, sine intermissione orate, in omnibus gratias agite. Haec est enim voluntas Dei in Christo Jesu in omnibus vobis. Quoniam necesse est quosdam in plebe esse immodestos, quosdam autem pusillanimes, hoc est, timidos, quosdam vero fide infirmos; ideoque hos qui moderati sunt et magnanimes, et fide fundati, hortatur cum prece, ut his consulant, ut possint proficere, sufferentes eos; ne si retributio fit malorum, pejores se fiant. Idcirco nihil aliud quam bonum sectandum hortatur non solum in causa fratrum, sed et in omnium. Possunt enim bonis operibus attrahi infideles ad credulitatem, ex qua semper gaudeatur in Domino, hoc est, in bonum. Orandum autem sine intermissione; sedulae enim preces provocant animum judicis ad dandam misericordiam. In omnibus vero actibus bonis Deo gratias agendas, qui hanc tribuit doctrinam in Christo Jesu Domino nostro. Ambrosiaster, In Epistolam ad Thessalonicenses Primam, Caput V Source: Migne PL 17.425b-c

And we beseech you, brothers, correct the disorderly, comfort the faint hearted, support the weak, be patient with everyone. Take care that no one returns evil for evil to anyone, but always follow that which is good for each other, and for all. Always rejoice. Pray without ceasing. In all things give thanks, for this is the will of God in Christ Jesus for all of you. 1 Because it is necessary that some among the people will be troublesome and some faint hearted, that is timid, and some weak in faith, therefore with a prayer he exhorts those who are self controlled and magnanimous and firm in faith, that they should care for those mentioned, so that they may be able to profit from bearing with them, lest if there be a reward for evils, theirs be worse. Therefore he exhorts that they should seek nothing else but the good, and not only for the sake of their brothers, but for all men. For with good works they can attract the faithless to belief, because of which there is always rejoicing in the Lord, that is, in the good. But there must be prayer without ceasing, for sedulous prayer inclines the soul of the judge to turn to mercy. And in every good act give thanks to God, who gives this teaching in Jesus Christ our Lord. Ambrosiaster, Commentary On The First Letter of Saint Paul To The Thessalonians, Chapter 5 1 1 Thes 5.14-17
