New Century Version
6 And if he chose them by grace, it is not for the things they have done. If they could be made God’s people by what they did, God’s gift of grace would not really be a gift.
7 So this is what has happened: Although the Israelites tried to be right with God, they did not succeed, but the ones God chose did become right with him. The others were made stubborn and refused to listen to God. 8 As it is written in the Scriptures:
“God gave the people a dull mind so they could not understand.” Isaiah 29:10
“He closed their eyes so they could not see
and their ears so they could not hear.
This continues until today.” Deuteronomy 29:4
