At times I find myself complaining, I tend to cover one of my eyes with my hand then I stop making a fuss.
My father lost his one eye because of an accident, he lost his hearing on his left ear because of sickness, he was operated and lost his appendix, and he almost lost his voice (now he barely talks loud) because he almost got drowned. Despite all of those he lost, I never saw him complain or question God. Instead, He always praises God when He looks back to his life.
Hard times come to test our endurance. God wants to see whether we will still praise Him in any season of our lives. And yes, blessed are those who love Him when lack and trials turn up.
