A good place to start is Mt. 25:31-46. OT reference to essentially the same thing is Is. 58.
Eph 2:9-10
10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
We are created in Christ for the purpose of these activities, because they are all for His glory. Every person is called to a different ministry, but each of us have deeds we are called to accomplish in life.
1 Tim 2:9-11
women should adorn themselves modestly and sensibly in seemly apparel, not with braided hair or gold or pearls or costly attire 10 but by
good deeds, as befits women who profess religion."
Good deeds are like an ornament, that brings the beauty of the spirit from one’s heart into the world.
9 Let a widow be enrolled if she is not less than sixty years of age, having been the wife of one husband; 10 and she must be well attested for her good deeds, as one who has brought up children, shown hospitality, washed the feet of the saints, relieved the afflicted, and devoted herself to doing good in every way. 1 Tim 5:9-11
Among these good deeds are faithfulness in marriage, being a good parent, being hospitable, serving the ministers of God, caring for the sick, and looking every day for ways to manifest God’s love to those around us.
24 The sins of some men are conspicuous, pointing to judgment, but the sins of others appear later. 25 So also good deeds are conspicuous; and even when they are not, they cannot remain hidden. 1 Tim 5:24-25
Good deeds, having been created by God, and springing from His Spirit within us to will and to do His good pleasure, bring the light out from under the bushel, and bear witness to the world of God’s love for mankind.
