Today is Yom Kippur, the Day of Atonement (Lev 16:1-34; 23:26-32). A deeper understanding of this day would lead to an increased understanding of what Jesus did on the cross.
Here's a short video about the sacrificial lamb produced by the good people at SourceFlix. (LOVE their videos!) Please take 10 minutes to share this your kids to introduce them to the importance of this day.
