Good works cannot produce salvation but are subsequent and resultant God-empowered fruits and evidences of it (cf. Jn 15:8 ; Php 2:12 , 13 ; 2Ti 3:17 ; Titus 2:14 ; Jas 2:16–26 ). which God prepared beforehand. Like his salvation, a believer’s sanctification and good works were ordained before time began ( see notes on Ro 8:29 , 30 ).
