Romans 5:1-5 - When our actions only come from duty or guilt or obligation, our actions have little life or purpose in them. Though a lot of good is done with motivation like this, it's not the type of obedience that the Bible talks about. Our good works and our following of the Bible comes BECAUSE we are right with God, not IN ORDER TO get right with God. Though this type of motivation does not come naturally, it is what we are to pursue. This is why we have the Bible and each other - to grow our faith in the One who speaks truth.
