Laodicea - The Blah Church Called to Blessing

This is a warning to us all that true Christianity must be full of life and zeal. We must not fall into half-heartedness.
Lukewarmness is sickening to the Lord, and we will be spewed out of his mouth, treated as sickening.

So, we must take heed to this letter. It is the worst church of the seven and has the strongest message warning us about growing lukewarm in our faith and work for Christ.
