But there were also false prophets among the people, just as there will be false teachers among you. When we reject such as truth, we are told we are faithless, or blasphemous at worst. Yet, when the Church begins to accept new things from God based on subjective experience - the door is open to bring in a host of deceptions as new works of God. No safeguards exist then for the Bible is no longer the object of faith and truth. Remember, God says we walk by faith and not sight.
Sight is a reference to sensual and visual experiences.
We are not to trust them. God warns us not to look to our senses, our sight, our feelings, or even outward manifestations - they all can be used by Satan to deceive. For God would not deceive us, or bring us things we cannot validate by His own standard. Friend, I don't believe this appearance of holy laughter or giggles for God is simply an oddity. It is another stage and preparation of the masses, to accept spiritual things based solely on the approval of spiritual leaders, and personal experiences.
