<p>9:37 <i>Jesus said to him: You have both seen him, and he it is that speaks with you</i>- 'Seeing' in John means 'understanding in faith'. The Lord is saying that the man has indeed figured things out correctly. In literal terms, the man had to be first given the gift of sight in order to see the Lord. And there was a spiritual equivalent. There is an element of calling, of enlightenment by the Spirit (Eph. 1:18); so that within the final algorithm of human salvation, there is the factor of God's grace. This is why Paul starts talking about predestination and calling in Romans; they are parade examples of how salvation is by grace and not of works nor of human tenacity or correctness of Biblical interpretation. These things are not outside of the algorithm, but they are not the only factors, lest salvation be of works and human ability.</p>
