Then you shall delight yourself in the LORD; and I will cause you to ride on the high hills of the earth. Isaiah 58:14
The above verse is a conditional Promise. In verse 13 Jehovah instructs the house of Jacob to turn back their foot from fulfilling the pleasures of this world on His holy day. They were to call the Sabbath a delight and honor it, not doing their own ways, nor finding their own pleasure and speaking idle words. They were to keep the Sabbath by enjoying God but if they did not keep the Sabbath in this way, they would be those who do their own ways, find their own pleasure, and speak idle words.
In the book of Isaiah, God makes Christ the centrality and universality. God wants us to learn one lesson—to keep away from the taste of anything other than Christ. We should be replaced by Christ and enjoy God continually. We should not engage in doing our own pleasure; we are to regard it with delight and to esteem it a day worthy to be honored, and we are to show respect to it by not performing our own ordinary works or pursuing pleasures. This is the purpose for which Christ died for us and was resurrected for us. He is our Sabbath and our food. Now we can rest in Him, feed on Him, and have Him as our replacement in every way and in everything. We should delight ourselves in the LORD- In His goodness and faithfulness to us, and in the assurance of His favor. And the LORD will cause us to ride on the high hills, which means “to live above the world, to be in the utmost safety and enjoy the greatest plenty, especially of spiritual things.” May God help us to delight ourselves in the LORD!
