The Church Visible and Invisible

The theme of the book of Hebrews is " no turning back".
We belong to a kingdom that cannot be shaken; believers have come and and have access to the heavenly realm.
As we gather for worship we are not alone.
The church is visible and invisible; what is physically seen and what is understood by faith.
We are told what worship is like in heaven,as a pattern to follow. it is better to worship poorly in the correct way, than incorrectly with skill.
Praise is speaking well of God, worship is sustained obedience.
