It is not punishment. God never punishes. And He well knows how you have been longing to do His will. This sickness has been given you as a loving message to help you understand that there was a still higher and more heavenly way of reacting to the wounds and troubles that you were experiencing than you knew about. Certainly God gave you a glorious victory even though your feelings were so wounded; you were delivered from resentment and were able to accept it all with forgiveness. But perhaps there was a little self-pity because you did not realize about the glorious principle I have been sent to share with you. For there is a still higher level of acceptance possible, and that is to accept everything that happens with praise, thanksgiving, and joy, knowing that every seeming affliction is really a blessing in disguise. God allows only the very best things possible to happen to you at any particular time; that is to say, exactly the things and situations that are best fitted to help you, because they afford you the opportunity of reacting just as Jesus did. Learning by His grace to react with praise and thanksgiving even to things that appear most evil, unjust, cruel, and deplorable, because God is allowing this opportunity to bring good out of evil, is just like waving a magic wand over an evil enchantment and being able to replace cruel spells with heavenly miracles.
