You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you! [Isaiah 26.3]
Peace is conditional. Period.
The absence of peace declares unbelief in God. In this way, peace is our guide to God.
If we see this through, we will understand the significance of the first three of the Ten Commandments:
“I am the LORD your God, who rescued you from the land of Egypt, the place of your slavery. “You must not have any other god but me. “You must not make for yourself an idol of any kind or an image of anything in the heavens or on the earth or in the sea. You must not bow down to them or worship them, for I, the LORD your God, am a jealous God who will not tolerate your affection for any other gods. I lay the sins of the parents upon their children; the entire family is affected—even children in the third and fourth generations of those who reject me. But I lavish unfailing love for a thousand generations on those who love me and obey my commands. “You must not misuse the name of the LORD your God. The LORD will not let you go unpunished if you misuse his name. [Exodus 20.2-7]
If we can see it then, God's commandments regarding singular trust in Him ALONE are commandments of peace.
What's more amazing is that the 4th Commandment regarding observance of the Sabbath, Who is Jesus, is all about rest. Peace and rest go together perfectly.
Now, contrast what is said above with the restrictive interpretation of these commandments we have had for so long. It is worthy of a long "ponder..."
Furthermore, think about all the turmoil associated with life these days particularly as it relates to man's do-it-for-himself systems of finance, insurance, medicine and technology... and even religion. These industries all purport to make "life" better, but do they? Rarely, if ever, are these industries praised for bringing peace to anyone. And, that is precisely why God demands that we trust Him ALONE instead of these idols! Idols cannot bring peace.
Peace comes only from trusting God, and that, in particular, from trusting God ALONE. God graciously refined this trust even further when He came to earth in the flesh and the angels made their declaration:
That night there were shepherds staying in the fields nearby, guarding their flocks of sheep. Suddenly, an angel of the Lord appeared among them, and the radiance of the Lord’s glory surrounded them. They were terrified, but the angel reassured them. “Don’t be afraid!” he said. “I bring you good news that will bring great joy to all people. The Savior—yes, the Messiah, the Lord—has been born today in Bethlehem, the city of David! And you will recognize him by this sign: You will find a baby wrapped snugly in strips of cloth, lying in a manger.” Suddenly, the angel was joined by a vast host of others—the armies of heaven—praising God and saying, “Glory to God in highest heaven, and peace on earth to those with whom God is pleased.” [Luke 2.8-14]
And then, Jesus Himself defined it clearly as well:
I have told you all this so that you may have peace in me. Here on earth you will have many trials and sorrows. But take heart, because I have overcome the world.” [John 16.33]
In perfect harmony with the Ten Commandments, Jesus gave us the exact recipe for peace:
If any of you wants to be my follower, you must give up your own way, take up your cross, and follow me. [Matthew 16.24 (also, Mark 8.34 & Luke 9.23)]
Father in heaven, for all that I have ever understood of Your Commandments, I see today that when I fully embrace them, they bring me peace. I see that when I give up my own way, take up my cross, and follow Jesus, there is peace.
