The grief and sorrow drive you more into God. It is just as when it gets colder outside, the temperature kicks the furnace higher though the thermostat. Similarly, the sorrow and the grief drive you into God and show you the resources you never had. Yes, feel the grief. There is a tendency for us to say, “I am afraid of the grief, I am afraid of the sorrow. I don’t want to feel that way. I want to rejoice in the Lord.” But look at Jesus. He was perfect, right? And yet he goes around crying all the time. He is always weeping, a man of sorrows. Do you know why? Because he is perfect. Because when you are not all absorbed in yourself, you can feel the sadness of the world. And therefore, what you actually have is that the joy of the Lord happens inside the sorrow. It doesn’t come after the sorrow. It doesn’t come after the uncontrollable weeping. The weeping drives you into the joy, it enhances the joy, and then the joy enables you to actually feel your grief without its sinking you. In other words, you are finally emotionally healthy.
