'Worship' is the term we use to cover all the acts of the heart and mind and body that intentionally express the infinite worth of God. This is what we were created for, as God says in Isaiah 43:7, Everyone who is called by my name, and whom I have created for my glory. That means that we were all created for the purpose of expressing the infinite worth of God's glory. We were created to worship.
