I have a testimony of the Gospel of Jesus Christ and I know that Joseph Smith was a Prophet of the Lord. I know the Lord knows ME and knows my fears of brain tumors and cancer risks, but that He also is with me celebrating my joys (when I am with my nephews, for example). And celebrates with me as I heal physically and mentally.
Today, Thomas S. Monson is the Prophet and receives revelation from Heavenly Father on behalf of the members of the church. I am thankful to have the Gospel in my life during this upheaval of brain tumors and genetic conditions. I am holding onto the iron rod with every ounce of strength I have!
