"Yet the chief butler did not remember Joseph, but forgot him." Genesis 40:23
Joseph gets accused by Potiphar's wife of rape, and is consequently thrown into jail. He remains there for several years, serving a sentence he did not deserve. And even when he helps interpret the bulter's dream and he implores him to remember his case when he gets out, he is forgotten. Despite the fact that Joseph has done nothing wrong, he suffers. Even though he is forgotten and ignored by man, God does not forget him.
Several years seems like a long time to endure in the jail, especially for a crime you didn't commit. But in the scope of Joseph's life, it was a mere fraction. Looking back with hindsight, his hardships are minor in comparison to the blessings and prosperous years that he lived. Although everyone in his life seemed to fail him, God never did. These years of suffering were not a result of God's neglect, but rather they were necessary events to bring him into a place of exaltation. The tears and pain had their purpose.
In our lives, tough moments may seem to linger long especially when strength deplete so quickly. However, we don't know the entirity of our lives. These moments are insignificant in terms of eternity. We do not know the purpose of these times of agony; we simply have to trust that God will never forget us. Though man shall fail us, though we might fall, God will always remember us. We just have to wait for Him to bring all the events of our lives, both good and bad, together in perfection.
