Offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. ~ Romans 12:1
Unfortunately many church leaders have hijacked the word "worship" and redefined it as a music session or a song set built to get a congregation "in the right mood".
God's intention of worship has nothing to do with a church service. His design of worship is built on a transforming relationship with Him - based on grace, gratitude, and humility.
Worship should look like giving yourself as an offering to God. Worship is what gives your life power. Worship builds a deeper relationship with God.
This is why you should worship - individually and collectively. It moves you from where you are into a transformational relationship with God.
And yes... the church gathering is a great place to worship collectively. Don't blow it off.
