Fear and trembling is through out the bible concerning those who
have grown in the power of the Holy Spirit. It is written the
demons worship and tremble also, yet this demonic trembling is more
a shuddet with convulsive jerking type movements of the body. the
holy Spirit trembling is smoothe trembling visually seen from the
feet to the top of the body trembling in one continuous wave .We
are to work out our salvation in fear (reverance) with trembling,
in other Words pursue God with all our heart and all our strength
not giving up to adversity. Christians should all come to the point
of trembling with Holy Hands raised.
