Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Without good works our Christianity, our walk with God after salvation, can become a mere religion of words. Men are said to be saved so that good works may result. Not works for salvation (Ephesians 2:8, 9) but works from salvation Ephesians 2:10. Grace is the total, complete work of God for man, out of which should come the faithful work of man for God as a response. Not works for salvation, but works from salvation.
Every Christian passes through the creative hand of God a second time and becomes a new creation (the workmanship of God) that God ordained to do good works. Men cannot see our light inside and that we are no longer in darkness. Men cannot see our faith. It is invisible. Men cannot see we are a new creation inside, but they can see outward evidence of that inward change. The shine of the light from inside of us is the works we do outside.
Matthew 5:14-16, “Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” It is not merely natural to do good works for God, it is supernatural. They come from motivations within our spiritual nature. Good works come from our walk with Him. After we get saved, we are to get your walk outside to measure up to His work inside. Our life is not to be lived unnoticed. We are not Christians undercover or secret service Christians. Isaiah 60:3 says, “And the Gentiles shall come to thy light, and kings to the brightness of thy rising.” This has to do with our doing good works. Our good works are the shine of the light.
