Heb 4:9 There remains therefore a rest for the people of God.

A quick definition is to cease work or movement in order to relax, refresh oneself, or recover strength.
So when Hebrews says there remains a rest for us, we often think of a cessation of struggles, trials, and tribulation in this life.
That is true, however, I also think we get a rest from vigilance.
It is written in 1 Peter 5:8 – Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.
You can never fully relax as a Christian.
You must keep vigilance on what you say and what you do – at all times!
The nature of sin is ever-present and you cannot let your guard down or it will get a foot in the door.
This vigilance is tiring because you are constantly on watch against temptation.
Temptation can produce struggles, trials, and tribulation as it wars against you.
We’re not quite there yet but the day is coming.
