Holiness and deliverancs is readily accessible in mount Zion. Obad1:17 Jer6:14
However this doesn't seem so with the saints because we believe blindly. We were made to believe that the supernatural is not meant to be understood by reasoning.
We must have a scientific understanding of our experience of God.
In science we deal with facts and evaluate things empirically. Because of that results are reliable predictable and repeatable.
God has given us an open invitation to empirically experience the Supernatural Psalms 34:8 John4:24
To guarantee total deliverance there must be a scientific understanding. It is the understanding that grounds your faith. Matt13:19
