In this chapter Bob goes further about his personal connection with God. He collaborates with his personal experience with worship, and he tells users to focus on serving, but not to take things other than God in mind. He points out that worship is about serving our holy savior and helping others connect with him through the process. If we ignore the basic fact about worship, then worship we are doing is not worship.
I think it is very important to keep remind ourselves about the greatness of our God. It's because of him that we are alive and miracles happen. Worship's purpose is to praise the Lord for what he had done for us. It is also a way that we get to express our feelings to God, to connect with him. If such a practice is filled with our own desire, then the intention will be impure. Thus, it is important to stay true for our hearts and focus on communicating with the Holy Spirit.
