Tim Keller in his book Every Good Endeavor writes, “When Jesus calls all people to himself, he says he knows we are “weary and burdened” and that we need “rest.” But Jesus’s cure for our weariness is a “burden” (verse 30) and even a “yoke” (verse 29)! The yoke or harness put on a beast of burden was a symbol of slavery and grinding toil. How could this be a solution to the problem of deep weariness? Jesus says that it is his yoke and burden—and it is the only one that is light. Why? “For I am gentle and humble in heart, and you will find rest for your souls” (verse 29). He is the only boss who will not drive you into the ground, the only audience that does not need your best performance in order to be satisfied with you. Why is this? Because his work for you is finished.” (loc 2,906).
