There is no other God. So, there is nothing else worthy of worship.  When we give our best affection to anything else, that thing is stealing from God the praise that belongs to him alone. It is also stealing from us the gracious privilege of connecting with the only God in worship.  Worship is not limited to liturgical activity such as song and prayer. Worship is any response to God that treasures his sovereignty. We respond to his sovereignty with adoration, surrender, repentance, submission, reverence, joy, serving our neighbor, loving our family, anything that is in line with his value, and it is all worship.  Do you have to go grocery shopping today, clean your house, have a difficult conversation? Do those things in a way that values God and you will be worshipping him.
