52:17-18 Surely the godwary will be in gardens and bliss, rejoicing in what their Lord has given them.
These verses demand hope.
The Lord of the worlds keeps them following one after another so that the servant is constantly traveling between hope and fear. Hope and fear are each other's mates. When they come together, the beauty of faith's realities shows its face. Any traveling that is empty of these two meanings will result either in security or in despair, and these two are attributes of the unbelievers. This is because one feels secure from the incapable, and to believe that God is incapable is unbelief. One despairs of the base, and to believe that there is baseness in God is associationism.
Also, one must not simply fear punishment, nor must one simply hope and wait for mercy. This will become clear to you with an example: When a lamp has no oil, it gives no light. When it has oil but no fire, it gives no illumination. When there are oil and fire but no wick to sacrifice its being, it is not complete. Thus fear is like fire, hope like oil, faith like a wick, and the heart like a lamp-holder. If there is only fear, this is like a lamp that has no oil. If there is only hope, this is like a lamp that has oil but no fire. When fear and hope come together, the result is a lamp that has both the oil to aid in subsistence and the fire to give material of illumination. Thus faith takes help from both, one for subsistence and one for illumination. The person of faith travels on the road with the escort of illumination and walks with the escort of subsistence.
