"Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Spirit" (Romans 15:13)
"Ye shall receive power." By those words our Lord raised the expectation of His disciples and taught them to look forward to the coming of a supernatural potency into their natures. It was to be nothing less than God Himself entering into them with the purpose of ultimately reproducing His own likeness within them.
Here is the dividing line that separates Christianity from all occultism and from every kind of oriental cult. They each advise, "Get in tune with the infinite," or "Wake the giant within you," or "Tune in to your hidden potential" or "Learn to think creatively."
All this may have some fleeting value as a psychological shot in the arm, but its results are not permanent because at its best it builds its hopes upon the fallen nature of man and knows no invasion from above.
Oh, how long we struggle! Oh, how hard we try!
Helplessly we labor; Helplessly we sigh
Till Thy Spirit gives us
Power from on high.
