Your motivation in life. Your mental attitude in life. Your spiritual status quo. Putting your brain systematically to work becomes power. Concentration is a matter of your priorities in life.
Worship demands concentration whether in learning, applying, praying, or in the communion service.
Again, worship is not a feeling but a system of thinking. Good decisions are made from thinking divine viewpoint. To neglect the discipline needed toward learning the word of God ultimately leads to the rejection of the word of God itself. A sign of worship is that we are humble and do not let distractions keep us from the plan of God. To accept advice from the cosmic system's human viewpoint, whether through your own stupid decisions or from the bad advice of others, only leads to the believer entering into the arrogant skills.
