And yet we have Jesus saying here in John 12:47.......
If anyone hears my words and does not keep them, I do not judge him; for I did not come to judge the world but to save the world.
Because in verse 48 there is the answer. When Jesus was on earth He was there to save. Then we have His Word. That will condemn the unbeliever.
48 There is a judge for the one who rejects me and does not accept my words; the very words I have spoken will condemn them at the last day.
