If the teacher is truly a servant of God, who’s goal is to do God's will, then serving such a teacher becomes non-different from serving God. This is because the servant of God works to please God. So pleasing such a servant of God will be pleasing to God. This confidential relationship between God, the servant of God, and the servant of the servant of God is the beautiful spiritual relationship that brings one into the fold of God’s kingdom. By honoring the teacher and servant of God (who also must be the servant of the servant of the servant of God), and following his or her instructions, we become pleasing to God, which develops our own personal relationship with God.
The rules of love in the spiritual world are actually quite simple. They are simple because they are actually a part of us. We are all originally created by God, and each of us has an instinctive relationship with Him that we at some point abandoned. Therefore, resuming that relationship is not difficult, but it requires determination. Prayer, praising God, offering to God, following God’s instructions; these are all very easy to do. They may be difficult to be consistent and it may be difficult to deal with all of our own desires, and the challenges and tests that are put before us. But if we just rely upon God--we will surely succeed.
One side point regarding Jesus’ last statement about “Beezlebub:” This was the term used to describe someone who opposes or rejects God. Many scholars point to the worship of Ba’al in the Old Testament as the source of this connotation. In other words, someone who rejected the worship of God by worshiping demigods or idols. Some further define this connotation as describing ‘lucifer’ or ‘satan.’ In this context, these two names are often referred to as fallen angels who now serve to tempt and tease those in the physical world. While this is certainly an acceptable connotation, we must also realize that those of us here in this physical world away from God are here because of our own choosing. We are each fallen angels. Those who reject or ignore God’s existence while reveling in the temporary pleasures of the world--and giving our lives to materialism are all part of the ‘lucifer’ and ‘satan’ clan. Therefore, we cannot blame satan or the devil for our predicament. Being here, away from God, is our responsibility. It is based upon our previous and current decisions to turn from God.
Yes, we each rejected God and fell down into this physical world. This is the analogy of adam and eve and the garden of eden. This does not mean that we cannot go back Home, however. We certainly have the choice to change direction--at every moment. With every tick of the clock brings a new opportunity for us to choose between God and our own selfish desires. This choice is always ours.
