This Song talks about how God is there for us in times of trouble. Nobody will be there for you in times of trouble, except God. That's why he said in his word that, call upon me in times of trouble. The only one you can call upon is not your mother, father, brother or friend. They cant be there for you, they cant die for you. you would be left in the problem, so look up to God, he alone that is with you, to pass through it with you, to bring you out to give you victory.
