I know Christians who choose not to follow certain counsels of Christ. For example, they would not forgive someone they dislike, they just can't. Yes, forgiving your enemy can be most difficult, but deciding not to forgive is going directly against the will of God – certainly the wrong attitude. The smart, right attitude is to tell God it's hard for you to follow his will, but admit that he is right and you need his help. This change of heart exhibiting humility is absolutely crucial to your ultimate salvation.
