The problem with many of us is that Jesus Christ really isn't Lord of all. Yes, we come to church - pretty regularly, at that. We give money, we sing songs, but down deep inside, we are still lord of our own lives. And if Jesus Christ really isn't Lord of all, we may as well change the lyrics to many of our worship songs. Worship goes way beyond a song.
Worship is a lifestyle.
A lifestyle that points to Jesus Christ as Lord and Savior our lives. These people come near to me with their mouth and honor me with their lips, but their hearts are far from me. Their worship of me is made up only of rules taught by men. Church, worship is much, much more than just singing a song. Worship must be backed up with action.
