Real healing is what promised us i do not see it happen like it happend in the bible , its not hard to accept that either jesus is lying, the bible is corrupt or we are not the followers of christ , these are the only 3 options. i take these verses from mark because for me they are the most hardest contradictions and they would make any rational bible believer a atheist
You could go with we have not enough faith but i highly doubt that of the billion christians.
You trust in a spirit in you and this is your authority ? but you can not confirm what the spirit tells you is true, you cannot even confirm that your spirit is not just some feeling you have , even paul says if you do not belief me lets your people who prophecy confirm that i am telling is the truth , meanwhile there are billion christians and their spirit tells them something else and there is nothing to confirm
