That's life.
If life would be easy, there will be no lesson. As a human being, we're all here to learn. Just remember that God is greater than ups and downs.
Indeed. Life is never gonna be easy because God wants us to learn something. He gave us free will to choose our destiny and face all the consequences. Life will always be unfair. All the challenges and complicated things we face in our daily lives makes our life more exciting and worth to live.
