Unbelief can blind us to so many beautiful and actual realities. When the truth blinds us, hope slowly starts to be taken away. Without truth and hope, we are setting ourselves up for failure and more suffering.
But, have no fear because beliefs are choices!
Remember, unbelief and belief all come down to choices. You do get to choose what you believe. If you want to believe in something where you have disbelief start asking and believing for it. In time and with perseverance, you will begin to believe. You must encourage and kindly remind yourself every day that you are consciously deciding to put your focus and beliefs over here and no longer over there.
The goal is to come out of agreement with your unbeliefs and into agreements with the beliefs you desire. How do you do this? By consciously choosing to move forward with those beliefs. Depending on how long your agreement has been with a belief will depend on how easy or difficult it is to change, but it can and will occur if you choose.
