The New Testament calls the Christian life a race. But it’s a race with pitstops. 

Our Lord Jesus came apart to rest at certain points in his public ministry.
 
One reoccurring theme is rest/enjoyment.

2:24 – “…eat and drink and tell himself that his labor is good.

3:4 – “A time to weep, and a time to laugh; a time to mourn, and a time to dance.”

3:12 – “… rejoice and to do good in one’s lifetime”

3:22 – “… that man should be happy in his activities …”

5:19 – “… eat from them and to receive his reward and rejoice in his labor …”

9:9 – “Enjoy life with the woman whom you love all the days of your fleeting life …”

Don’t feel guilty when you have special air mattress moments!  They’re from the Lord for your good.
