Romans 10:8

But what saith it? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach:

'But what saith it?' -'What does it say, then? This!' (Bruce p. 204)

'The word is nigh thee, in thy mouth, and in thy heart'

'The righteousness which is of the law (that is, earned righteousness) asks for (in practice) the impossible. The righteousness which is of faith asks for what is easy to give; that is, submission, by faith, to Jesus as Lord. To seek. righteousness of our own is to act as though Jesus had never come, died and rose again (Romans 10:6-7). To seek, by earning, God's righteousness is to act as though Christ had not obtained for us the righteousness of God. The will of God as laid before Israel by Moses was not difficult to understand, it wasn't beyond their capacity, it wasn't inaccessible to them. They didn't have to be supermen to do it. They didn't have to be Einsteins to understand it. They didn't have to be Marco Polo to travel to distant regions to find it (Read Deuteronomy 30:11). God had made it available to them! God had placed it within their ability! Moses simply called on them to then submit to God's desires out of love for Him (Romans 30:6)....this was what the righteousness which is of faith called for. It called for people to lovingly submit to. Lord who had done everything for them. (Now all of this had the aim in view of reminding the complaining, whining Jews that they didn't NEED to be whining in their unblessed condition.)'

All that 'faith-righteousness' requires, is that you believe/accept/embrace with full trust the gospel message (Romans 1:16; Acts 2:38; Acts 2:41). And that's not an impossible task for anyone!

These are great passages for those that claim the Bible is too confusing! Or, it is impossible to live the Christian life.
