Rest

In Exodus 33 the Lord gives Moses this promise:  "My Presence will go with you, and I will give you rest."  What was the rest that the Lord had promised to Moses?  In Psalm 95 the Psalmist says that the Lord in His anger at the people for their complaining said that they would never enter the rest.  It would seem that the rest was associated with the land of Canaan.  The writer of Hebrews also seems to indicate this in Hebrews 3 but then in the next chapter he indicates that this promise of rest still stands today.  There was something more than the promised land.
Moses never entered the land but he did receive the rest that the Lord promised to him.  The rest he received was the promise of God's presence.  We can experience that rest when we know that the promise of God's presence will be with us.  Remember the words of Jesus who said, "Go ...and surely I am with you always, to the very end of the age.”
When we know that the Lord goes with us we can be assured of His rest.  When we do things in our own strength we find that we do not have that rest.  When God sends He goes along side and He is our rest.
