American biblical scholar, Jeff Benner that wrote the Hebrew Lexicon, as an interesting view to share in his word study of the word, 'saviour'. He wrote, 'God is not one that has delivered (past tense), he is not one that will deliver (future tense), he is the one that 'IS DELIVERING' (present tense).
