Tell your family that, if they want to talk to you, they must find someone else in the house to “connect” the two of you. The “connector” must hold your hand and a hand of the person who wants to talk with you. After playing this game awhile, explain that the person who serves as a connector is a “mediator.”
People need a mediator because of sin. God, who is holy, must separate himself from sinners. Jesus is called a mediator because He reconciles, or connects, us with God. Because Jesus suffered and died for humankind’s sins, He has become the perfect mediator between humans and God.
1 Timothy 2:5-6
