On Good works:

What shall we do, then, brethren? Shall we become slothful in well-doing, and cease from the practice of love? God forbid that any such course should be followed by us! But rather let us hasten with all energy and readiness of mind to perform every good work. For the Creator and Lord of all Himself rejoices in His works. For by His infinitely great power He established the heavens, and by His incomprehensible wisdom He adorned them. He also divided the earth from the water which surrounds it, and fixed it upon the immoveable foundation of His own will. The animals also which are upon it He commanded by His own word into existence. So likewise, when He had formed the sea, and the living creatures which are in it, He enclosed them [within their proper bounds] by His own power. Above all, with His holy and undefiled hands He formed man, the most excellent [of His creatures], and truly great through the understanding given him--the express likeness of His own image. For thus says God: "Let us make man in Our image, and after Our likeness. So God made man; male and female He created them." Having thus finished all these things, He approved them, and blessed them, and said, "Increase and multiply." We see, then, how all righteous men have been adorned with good works, and how the Lord Himself, adorning Himself with His works, rejoiced. Having therefore such an example, let us without delay accede to His will, and let us work the work of righteousness with our whole strength.

The good servant receives the bread of his labour with confidence; the lazy and slothful cannot look his employer in the face. It is requisite, therefore, that we be prompt in the practice of well-doing; for of Him are all things. And thus He forewarns us: "Behold, the Lord [cometh], and His reward is before His face, to render to every man according to his work." He exhorts us, therefore, with our whole heart to attend to this, that we be not lazy or slothful in any good work. Let our boasting and our confidence be in Him. Let us submit ourselves to His will. Let us consider the whole multitude of His angels, how they stand ever ready to minister to His will. For the Scripture saith, "Ten thousand times ten thousand stood around Him, and thousands of thousands ministered unto Him, and cried, Holy, holy, holy, [is] the Lord of Sabaoth; the whole creation is full of His glory." And let us therefore, conscientiously gathering together in harmony, cry to Him earnestly, as with one mouth, that we may be made partakers of His great and glorious promises. For [the Scripture] saith, "Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which He hath prepared for them that wait for Him."
