The saints of Scripture kept God's commandments
Thesis X. Experience itself proves most clearly of all that the faithful can keep God's commandments through God's grace, since Scripture testifies that many holy and devout people actually kept them. David does not hesitate to say so of himself in Psalm 119: 'I made haste and did not delay to keep your commandments' (margin: Pausa Heth); and again, 'My soul has kept your testimonies and loved them dearly. I have kept your commandments and your testimonies, for all my ways are before you' (margin: Pausa Schin).
Luke the Evangelist gives the same testimony of Zechariah and his wife Elizabeth: 'Both were righteous before God, walking blamelessly in all the commandments and ordinances of the Lord.' Indeed, Scripture often describes all the devout and faithful as those who keep God's commandments, as when David says in the same psalm, 'I am a companion of all who fear you and keep your commandments.'

X. Verum fideles per divinam gratiam posse Dei mandata servare omnium evidentissime probat ipsa experientia. Nam, Scriptura teste, multi sancti & pii homines de facto Dei mandata servarunt. Id de seipso David affirmare non veretur, Psal. 119. [marg.: Pausa Heth.] Festinavi, inquit, & non tardavi custodire mandata tua. Item, [marg.: Pausa Schin.] Custodivit anima mea testimonia tua: & dilexit ea vehementer. Servavi mandata tua & testimonia tua: quia omnes viae meae in conspectu tuo. Lucas autem Evangelista idem testimonium perhibet de Zacharia & Elizabeth illius uxore. Erant, inquit, justi ambo ante Deum, incedentes in omnibus mandatis & justificationibus Domini, sine querela. Quin omnes pii & fideles in scriptura frequenter describuntur per eos qui mandata Dei custodiunt: Ut quum dicit David psalmo modo citato, Socius ego sum omnium timentium te, & custodientium mandata tua.
