Absolutley agree that by faith we are saved as it is a free gift. But we know the tree by its fruit. The works of keeping the commandments is the fruit. Salvation is a free gift by the grattitude of this free gift we strive to keep his commandments.
1 John 5

1 Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.

2 By this we know that we love the children of God, when we love God, and keep his commandments.

3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
