Have children sit quietly with their heads down and eyes closed. Choose one child to be “Contagion.” Have Contagion go around as quietly as possible. When Contagion taps someone on the shoulder, that child gets up and puts their hands on Contagion’s shoulders, forming a chain. They continue to move around as quietly as possible. Contagion continues to tap people until everyone is in the chain. Tell children that sin is like Contagion. It spreads everywhere and to everyone until we are all caught up in it.

Divide children into two teams and have teams line up single file. Give each team an empty bowl and spoon. On the opposite side of the room, place the large bowl of mini marshmallows (representing sheep—Abel’s offering) and corn kernels (representing crops—Cain’s offering). On “Go,” the first child on each team must run across the room to the large bowl and scoop only marshmallows out with the spoon. When the child has a spoonful of marshmallows, he or she must return to the team and place all marshmallows left on the spoon into the team’s bowl (any marshmallows that drop must be left on the ground). They then give the spoon to the next child, who repeats the process. Play continues for five minutes. The team with the most mini marshmallows in their bowl after five minutes wins. If any corn kernels end up in a team’s bowl, they must subtract the number of corn kernels from their total score. Remind children that God accepted Abel’s sacrifice but not Cain’s, because Abel trusted God and his promises while Cain did not.

Have children spread out in the room. Choose one child to be the “Blob.” Start a game of tag. The Blob is “It.” When the Blob tags someone, the tagged child links arms with the Blob. Continue play until everyone is a part of the Blob. Tell children that sin is like the Blob. It spreads everywhere and to everyone so that we are all caught up in it.

Divide children into teams and have teams line up single file. Have the first child from each team crouch down and walk in this position as quickly as she can from the starting line to the other side of the room and back. When the first person returns to the starting line, have her tag the next person, who repeats the process. The first team to have all participants finish the race wins. Remind children that God warned Cain that sin was crouching at his door.
