When it comes to setting up goals in life, I tend to set small goals. The reason for that was because I don't want to give my hopes up and end up not getting the goals that I set up. But that mindset has been transformed since I have a relationship with God. I realized that I worship the almighty and powerful God. He is more than able to do the impossible and unthinkable things for us.
When you base the outcome on the things that you can and can't do, you are limiting His power to work in your life. Trust in Him and you will see the impossible things in life become a reality.
