Life can be an up and down affair. Our walk with Christ should not be. God is calling us to live in consistent communion with Him. He does not want our relationship with Him to fluctuate depending on our moods and emotions. There is a move away from emotion based worship because He wants relationship based worship. Relationship based worship worship far exceeds our emotional state and is born out of a love and passion for Christ. This love and passion is not affected by how we feel at a particular moment.
The only way this can be a reality is if we are transferred out of the kingdom of this world into the kingdom that Christ purchased with His own Blood. To truly be part of a kingdom you must be a resident, not just a visitor. Residents of a kingdom live with the privileges and protections that come from residing in the kingdom under the rule of THE KING!
