You know, the things you say and the way you say them practically demand that people have the word stupid come to mind. It is all they can do to not say it.
You think you are saved because you had the brilliance and good sense to choose to be saved. How is that not arrogant? How is that not saying, "I thank God I am not like one of those Calvinists who sit around waiting for God to choose them." To this say, "Thank you God that you saved me by grace and may I never think I deserved your grace by saving myself." God did not choose me because I am the apple of His eye, I am the apple of His eye because He chose me. But, going back to my first statement here, I do not expect you are able to even begin to understand that statement, so full of dependance on yourself and your superior wisdom in choosing to be saved, as you seem to be. Better to trust in yourself that to trust in God? And then call that chest thumping humility.
