Because God created Man to live in Peace, there is no way you can say "I tried my best" and believe this is what it takes for you to walk away, in Peace. There is no Peace in walking away from anything or anyone.
Because God IS Peace, there is absolutely no way He would give you directions to Peace as well as an alternate route in case you don't make it. There are no alternatives in God - there is only ONE way, ONE truth and ONE life!
To say "I tried my best" is going on your own strength, which clearly wasn't enough to accomplish your goals, hence your reason for walking away. You justify your feelings and/or actions by going as far as to say "God told me to walk away." God could never do such a thing because that would mean His original plan of Peace was a failure and so telling you its ok to walk away would be another way of accepting your failure. REALLY?!?!
This is the Ego's way of thinking and you must see it for nothing other than that. It occurs the moment you see another as a threat. At this point the Ego has pulled the wool over your eyes and is holding you hostage. You are no longer in control of how you feel, what you say and/or do because from this point, every decision made is from emotion (where logic does not exist.)
Only in knowing who you are is when you'll remember who your brother is, despite the disguises. If you've reached the point where you want to walk away because "you've tried your best", its because you can't see God in him/her. How could you walk away if you did? The only way you'll be able to see God in anyone is through the eyes of the Holy Spirit who has 20/20 vision. For humans, hindsight is 20/20!
Don't let the Ego continue to confuse you into believing when you feel you tried your best, God says its ok to walk away. God walks away from no one and would never tell you its ok. Choose rather to be led by the Holy Spirit Who will show you there is no threat and so no reason to walk away. When you've tried your best and haven't gotten to peace, know that's because your strength won't get you very far and if the Ego is running your life, you won't get anywhere at all which is why you're ready to walk away. Remember "ALL things are possible through Christ who strengthens me" and you'll accomplish your goal which is God's goal - Peace.
