You feel it enough and it is like a fresh Baptism with the Holy Ghost . If it has, you only know if you have the feeling. Feeling is the awareness through physical sensations. In my view, it is the most important function of art and science to awaken this feeling and keep it alive in those who are capable of it. It is in power and it is a profound feeling that reaches to the depth of your soul .
Experience is valid.
Those who have never experienced it are the ones that will tell you that you do not need feelings to validate the Holy Ghost. The spirit itself bears witness with our spirit, that we are the children of God. For myself, I trust my feelings. I know that God has put His witness in my spirit for a reason and when He witnesses to it, I feel it. It does not go against scripture but many times it confirms new truths that He teaches me.
