What does the Bible say about the struggles of life?

The Bible explicitly states that life is fraught with difficulties, a reality echoed in Job's declaration that human days are 'few and full of trouble.' Every person on this earth faces struggles, including insecurities and sin. For believers, there is a unique inner struggle with sin that adds to the challenges of life. However, Christians also have the promise that they are not alone in these trials, as God's people throughout history have experienced similar hardships. This shared experience serves as a comfort amidst life's difficulties.
