I believe that one has to purpose to worship. Though it is not our natural response to focus on anything else other than ourselves worship has to be intentional. Worship requires an intentional awareness that God is worthy of adoration. Worship is intentionally being conscious or aware that God is deserving of our affection. Worship does not happen on accident it has to be intentional and desired by the person who seeks to offer it. Psalms 105 suggest that we should always seek His (God) face. That is to always seek God’s presence. Seek denotes that you are intentionally looking for something. Thus, I conclude that worship is intentional.
