We are assured and know that (God being a partner in their labor) all things work together and are fitting into a plan) for good to and for those who love God and are called according to (His) design and purpose.
When a was a baby born again Christian i had a lot of anxieties and fears. Then i stumbled on that verse. To make it simple it says that i can be assured, with the help of God, that everything in my life is and will come together for my good. You can be assured too. God’s got our back in our everyday life. Receive that peace that comes from knowing that our lives are in God’s hand. To receive it just ask God.
