Romans 10:20-21

And Isaiah is very bold, and saith,. was found of them that sought me not;. became manifest unto them that asked not of me.

Romans 10:21 But as to Israel he saith, All the day long did. spread out my hands unto. disobedient and gainsaying people.

'In Isaiah (63-65) the people confess their iniquity but they refuse to take the blame squarely on their own shoulders. in Romans 63:17 it is God who is the instigator of the whole thing. in Romans 64:1-3 they lament that God hasn't been showing himself as he used to. The reason Israel has fallen away from him is his fault (7). Poor Israel! That "sorry old God" is to be blamed. In the passages Paul is calling on, God is making it clear he hasn't been hard to find. How could he be hard to find when he is being found by people who hadn't (even by Jewish admission) been searching for him? All around the Jews in Paul's society there was living Gentile proof that God isn't hard to find. In Isaiah 2:1 God had made that very response. No, he wasn't hidden. He was easy to find to those who really sought him. He had stood around all day holding out his hands to. disobedient and gainsaying people. They never saw him! The Jew didn't lack revelation; HE LACKED TRUST.'

The same is true today. Many people don't need more information or additional 'proof'. They simply need to believe the abundance of information that has already been presented in the Scriptures. On the judgement day, no one is going to be able to successfully plead, 'I couldn't believe do to lack of evidence'. (Romans 1:20)
