The human spirit possesseth wondrous powers, but it should be reinforced by the Holy Spirit. What thou hearest other than this is pure imagination. If, however, it be assisted by the bounty of the Holy Spirit, then will its strength be a thing to marvel at. Then will that human spirit uncover realities, and unravel mysteries. Turn thy heart fully to the Holy Spirit, and invite others to do the same; then shall ye witness wonderful results.
