If you are a Christian, who is carrying a heavy load that God hasn’t seen fit to lighten or remove, don’t give in to bitterness, rebellion, or self-pity.

When your emotions well up, as they inevitably will, think about apostle Paul. He had an affliction that God never saw fit to remove. Be honest with God, he understands. As long as you keep your life open to him, your affliction will never touch your heart.
