Right out of the chute, the author has the Gospel wrong. His info may be from the "Gospels", but this is not the "Gospel". Go read Paul's letter to the Romans. In the Gospels, Jesus was teaching the Jews that if they want Law to be their salvation, here is what is involved...perfection. Otherwise, God will grant faith to those whom He has chosen (by grace, alone) and rescue them because He has decided. No wonder the author cannot see the picture...he has been blinded by "religion".
I love my neighbor enough to try to save him from his sin. Just sayin’.
