Read Hebrews 4 today.

As I read this chapter:
There is a ‘rest’ God has prepared for us.
Not everyone with the opportunity to enter God’s rest has done so, or will do so.
The reason for those who did not, or will not, is a lack of faith in their part.
The opportunity is there for us. Faith or not faith are our options.
Hebrews 4:1-2 NIV
Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it. [2] For we also have had the gospel preached to us, just as they did; but the message they heard was of no value to them, because those who heard did not combine it with faith.
