In the second half of Romans 4, Paul reiterates that we are saved by grace through faith. Not through any work, effort or righteousness of our own – but simply by believing what Jesus has done for us on the cross. He was delivered up for our transgressions and raised for our justification!
To help us understand and build our life on this amazing truth, and the freedom and security it brings, Paul points to Abraham as proof. He too was made righteous by faith, believing God’s incredible promise of a son. Abraham teaches us a lot about the nature of faith – that it rests on a revelation of God as powerful, gracious and committed to fulfilling His promises. When we see God clearly, we too can have this kind of faith. And it changes everything!
