Why faith is important

The reason Paul wrote Romans was to share the gospel and to teach us that our righteousness comes by faith in Christ, not by earning it. The first and second chapter of Romans talks about us being guilty before God, and that circumcision doesn't necessarily make them righteous in God's eyes. Chapters 3&4 talk about faith and how it's always been the means for justification, while 5 talks about how we are blessed through Jesus Christ. 6-8 talks about sin and how to live through Christ without sin and 9&10 talk about being saved through faith. What I think personally is the easiest thing to explain to a non believer is being saved by faith through Christ. Because all you have to tell them is if you  truly beleive in Christ you will be saved. Also, it's not only easy to understand but to do. Now on the other hand the hardest thing to explain would be sins. To a non beleiver it's allot to take in because they are probobally just realizing that they've been living their life wrong. It's also a very intimidating for a non beleiver because it makes them feel bad about themselves and how blind they've been. And sinning in complicated. If you sin yes your forgiven so the question is, what's the point of obeying God's word and not sinning? The answer is if your a true beleiver and follower of God, you should follow His word and want to do what it says. Plus it makes your faith stronger in Christ the less you sin. So if you really live by what paul talks about in Romans, you should be a strong believer.
