Logic and reason are good for what logic and reason are good for. But in matters of the Spirit they often come up short.
For example: "The Spirit Himself bears witness with our spirit that we are children of God..."
This is not a witness in the mind of men, it is a witness in their spirits. Logic and reason cannot explain this because both are bound to the natural realm. Some may say "Well, this is just reading the Bible and agreeing with the verses." That would create a cognitive faith based on logic and reason. Such a faith, based on logic and reason, can easily be defeated by the same.
Sadly, what is sold to the people as spiritual is simply emotional (like the many videos and examples posted in the this thread and others). The enemy is not creative, he simply spins the same yarn over and over with differing machinations based on the times. To the spiritual, this is apparent, but the carnal are easily deceived.
Today, there is a separation occurring between the spiritual believers and natural believers. This was foretold:
"I will rouse your sons, O Zion,
against the sons of Greece."
Greece is the birthplace of philosophy and the teachings of logic and reason. In most churches there is a mixture. But, there is a day coming when the two camps will become distinctly separate from one another.
Now, some will say "How can you say that?" or "Who are you to say these things?" The logician will chase 666 with arithmetic formulas and old history books to try to discern the Day. The spiritual need only listen to the Spirit of God to be assured that, as they Day approaches, they will be prepared by Him. The truth is you get to decide for yourself whether or not what I say has any bearing on your life. To those who hear the Spirit of God, I am certain your time is not wasted reading my posts. To the sons of Greece: you would be better served playing Words with Friends. Alternatively you may ask God for wisdom and He will give it to you. The worst thing that could happen is that you win your freedom from a congregation who have denied the power of God and are consequently addicted to logic and reason.
