I will bless you if you honor the Lord's Day of Rest.

Blessed are those who honor My Sabbath Day of rest.

"If you refrain from trampling the Sabbath, from following your own pursuits on my holy day;
If you call the Sabbath a delight,
the LORD’s holy day glorious;
If you glorify it by not following your ways, seeking your own interests, or pursuing your own affairs—
Then you shall delight in the LORD,
and I will make you ride upon the heights of the earth; I will nourish you with the heritage of Jacob, your father, for the mouth of the LORD has spoken."  (Isaiah 58: 13 - 14).

The Sabbath/Sunday Rest is a very important institution in Judaism and Christianity. 
The Sunday Rest is a rehearsal for eternal rest which if you think of it is the main promise of Salvation.
"What good will it be for someone to gain the whole world, yet forfeit their soul? Or what can anyone give in exchange for their soul?"  (Matthew 16: 26).

"Blessed are those who honor my Sabbath days of rest and keep themselves from doing wrong."  (Isaiah 56: 2 NLT)

Sunday Rest comes once a week and reminds us of creation and the Resurrection of Jesus in a weekly rhythm that forces us to pause our hectic addiction to activity. 

He who keeps holy the Lord's Day is blessed in accordance with the promises. 

“Remember to observe the Sabbath day by keeping it holy. You have six days each week for your ordinary work,  but the seventh day is a Sabbath day of rest dedicated to the LORD your God. On that day no one in your household may do any work."  (Exodus 20:8-10 NLT)

"That is why the Lord blessed the Sabbath day and hallowed it [set it apart for His purposes]." (Exodus 20:11 AMP)
