“For in the Gospel a righteousness which God ascribes is revealed, both springing from faith and leading to faith [disclosed through the way of faith that arouses to more faith]. As it is written, The man who through faith is just and upright shall live and shall live by faith.” Romans 1:17 IOW – God ascribes this righteousness through His Son the Lord Jesus Christ. This righteousness grows in from the initial faith to believe in Jesus and as we move forward unto sanctification (being more like Christ – but it is like a snowball that gains mass, gets stronger as it grows). If in faith you make good choices in life, according to Christ’s precepts, then you shall LIVE and LIVE by Faith (again one accrues to the other). So powerful in so little words.
