When we read Luke chapter 9 we see what Jesus speaks to His disciples (including those He has chosen to be with Him at that time, and those who come to Him and try to follow too).
1. He speaks of and shows them the right motive for using His authority and the power of the Holy Spirit.
2. He speaks of the only way of receiving and using His authority and power: one has to totally let go of self. Otherwise, one does not qualify and will misuse them.
3. Jesus shows that the use of His authority and power is for good and not for evil. The motive (heart’s desire) of having them is to save and heal the weak and vulnerable, the poor, the sick, the lost and the oppressed.
4. He warns of the spiritual forces behind a man’s motive. True disciples must be spiritually discerning of the spirits affecting one’s motive.
5. He also warns of the hindrances from our flesh (refusing to let go of self).
