He most certainly sounds sincere. I found it to be incredibly sad. In all of His declared faith statements, I did not here him describing the pesonal love and presence connection that I have felt through Jesus and the Holy Spirit. This indescribably good phenomena has validated my step of trust. His presence has convicted my heart soul of His truth and the truth of His word.
I have seen seen prayers answered that that have had no explanation other than the supernatural and I have seen unanswered prayer. It never shook my conviction. The truth is faith is trust. If we are doubting why He does things we are not trusting. There are logical reasons why prayers don't get answered, but they are not all encompassing. From trust not being genuine to Paul who was told by Jesus the thorn in His flesh was intended to keep Him from getting prideful and relying on Him. The point being faith is trusting and relying on God, is so far beyond our mental capacity that we can not fully understand Him. The answer He gives to Job when calamity strikes. I personally had a great personal tragedy, a devastating blow to my heart and soul after I had already known His realness. I never questioned that He existed, but I was extremely angry with Him. My anger was out of the pain that was inflicted and he gently set me back on His truthful path. He has given us free will. People do horrendous things. God could control everything, but that is only robot making. Why would he be interested in that? It is only with the gift of freedom that we can experience a beautiful love that can be by no other way than freedom.
The answer for the battle of truth. The battle for the church. Is that freedom, the Spiritual Battle that even Satan attempted to use against Jesus by distorting God's word and what it means.
I would love to talk to the person in the video's and I am going to attempt to talk to Him. His story is a tragic one.
