Psalms 66:2

"But play ye to His name" (ver. 2). What hath he said? By you "playing" let His name be blessed. But what it is to "play"? To play is also to take up an instrument which is called a psaltery, and by the striking and action of the hands to accompany voices. If therefore ye jubilate so that God may hear; play also something that men may both see and hear: but not to your own name. ...For if for the sake of yourselves being glorified ye do good works, we make the same reply as He made to certain of such men, "Verily I say unto you, they have received their reward:" and again, "Otherwise no reward ye will have with your Father that is in Heaven." Thou wilt say, ought I, then, to hide my works, that I do them not before men? No. But what saith He? "Let your works shine before men." In doubt then I shall remain. On one side Thou sayest to me, "Take heed that ye do not your righteousness before men:" on the other side Thou sayest to me, "Let your good works shine before men;" what shall I keep what do what leave undone? A man can as well serve two masters commanding different things as one commanding different things. I command not, saith the Lord, different things. The end observe, for the end sing: with what end thou doest it, see thou. If for this reason thou doest it, that thou mayest be glorified, I have forbidden it: but if for this reason, that God may be glorified, I have commanded it. Play therefore, not to your own name, but to the name of the Lord your God. Play ye, let Him be lauded: live ye well, let Him be glorified. For whence have ye that same living well? If for everlasting ye had had it, ye would never have lived ill; if from yourselves ye had had it, ye never would have done otherwise than have lived well. "Give glory to His praise." Our whole attention upon the praise of God he directeth, nothing for us he leaveth whence we should be praised. Let us glory thence the more, and rejoice: to Him let us cleave, in Him let us be praised. Ye heard when the Apostle was being read, "See ye your calling, brethren, how not many wise after the flesh, not many mighty, not many noble, but the foolish things of the world God hath chosen to confound the wise." ...But the Lord chose afterwards orators also; but they would have been proud, if He had not first chosen fishermen; He chose rich men; but they would have said that on account of their riches they had been chosen, unless at first He had chosen poor men: He chose Emperors afterwards; but better is it, that when an Emperor hath come to Rome, he should lay aside his crown, and weep at the monument of a fisherman, than that a fisherman should weep at the monument of an Emperor. "For the weak things of the world God hath chosen to confound the strong," etc. ...And what followeth? The Apostle hath concluded, "That there might not glory before God any flesh." See ye how from us He hath taken away, that He might give glory: hath taken away ours, that He might give His own; hath taken away empty, that He might give full; hath taken away insecure, that He might give solid. ...
