Think about Jesus. Immediately after being baptized and filled with the Holy Ghost, He was led into the wilderness to be tested and tried by the devil. He did not complain and become discouraged and depressed. He did not think or speak negatively. He went through each test victoriously.
Can you imagine Jesus traveling around the country with His disciples talking about how hard everything was? Can you picture Him complaining about how difficult going to the cross was going to be….or how uncomfortable it was to roam the countryside with no bed to sleep in at night? You and I have the mind of Christ, and we can handle things the way He did: by being mentally prepared through “victory thinking”.
