The only reasons things are tested by what Paul tried to explain why letter verses your heart.
Romans 2:
28For he is not a Jew, which is one outwardly; neither
is that circumcision, which is outward in the flesh:
29But he
is a Jew, which is one inwardly; and circumcision
is that of the heart, in the spirit,
and not in the letter; whose praise is not of men, but of God. Personally experience is challenged by letters requirments.
