In John's vision he was given a glimpse of worship in heaven. Around the throne of God were four living creatures, the likes of which mankind has never seen.
These creatures never rest day or night (Revelation 4:8) because they are occupied with worshiping the Most High God.
The creatures in heaven worship God. Day and night. They praise His name. They bow down before Him. They acknowledge Him as Creator.
They are never too busy to worship. They are never too tired to give praises. They worship and give honor and glory. Day and night. No excuses.
Worship and praise and honor and glory belong to God. Even if human beings never worship Him - all praise and honor belongs to Him.
But God loves us and wants to save us and so He shows us this example of true worship. He wants us to practice worship on earth because there is, and will be worship in heaven.
We need to examine our hearts: what's preventing us from worshiping the Creator with all our hearts today?
