I cannot help you in your unbelief. But, there is coming an event which will give you an opportunity to change your mind and call out ‘Blessed is He Who comes in the name of the Lord’. Don’t let your bitterness block your heart from repentence at that hour. Shalom
Thank you for your admission that your belief in the "new testement" rests on absolutely nothing.
May it be His Will that you one day see the errors in this and acknowledge the true and pure Word of G-d.
