On Passover night we invite the children to open the door for and to Elijah. Why? The Passover is a family event. It brings together the generations, who, at times, do not want to be together. Still, the promise connected to Elijah is: “He will turn the hearts of fathers to the children, and the hearts of children to their fathers – else I will come and strike the land with utter destruction” (Mal. 4:5-6).
Sending the children to open the door for Elijah is an act of faith on the part of parents for continual relationship with their children, or for restoration in the family. Maybe it’s not the children sent, or the parents sending, but a hope for restoration in general. Once the door is opened for Elijah, the door is opened for the One he was heralding, Yeshua/Jesus, Who stands at the door, knocks (Rev. 3:20), and once He enters, He makes all things, even tense and broken relationships, new (Rev. 21:5).
Be well. Shalom.
