39.32 · Hostility, Strife · Strife, Struggle
to fight against God, to be against God, to be an enemy of God pertaining to fighting against God Although the figurative expression ‘fighting against God’ is an unusual and radical figure of speech, it can often be translated more or less literally, but in some languages such an expression is regarded as both impossible and even ludicrous, and therefore one must employ some such expression as ‘to be a constant enemy of God’ or ‘to be always against God.’
