Doctrine does matter.
Dead men do not cooperate with grace. Unless regeneration takes place first, there is no possibility of faith.
Jesus came to seek and to save the lost. He is the Seeker; we are the ones who are running.
To honor God as God, we must worship Him as He and He alone decrees.
Without God man has no reference point to define himself.
God is not going to negotiate His holiness... in order to accommodate us.
