I understand what you mean. It is easy to get frustrated and 'give up hope" for these folks ... But then we remember, 'Except for the grace of God, so go I'.
I know I was in worse shape, but yet God did not give me up to what I deserved. These people truly have been blinded by the god of this world, and they have our pity and prayers ... Romans 1 reminds us though, that there will come a time when God will give them up ... and that end will not be pleasant.
It is then a time to ask that He love them for us... for I do believe when He says as much as lies within you live peacefully with all men....HE recognizes our limitations and sometimes will take us to the point where we see them as well.
Thank you again....
