Suggestions for Christians on Yom Kippur
1. Read Leviticus 16, 23:26-32; Numbers 29:7-11, Isaiah 53, & Hebrews 5-10
2. Ask your Jewish friend what he is doing for Yom Kippur, etc. (He may be fasting and going to services or he may be doing nothing at all.)
3. Ask Jewish friends about their concept of sin and atonement. Discuss the sacrificial system. Challenge them to read Leviticus with an eye towards atonement.
4. Prepare a 1-2 minute testimony of what Yom Kippur means to you.
5. For educational purposes, attend a Yom Kippur service at a synagogue (paid seating is expensive, but free student seating is often available and some synagogues advertise free seating). I recommend the Kol Nidrei service at a Reform or Conservative synagogue. You might also visit a Messianic congregation if they have a service.
6. Fast, pray and mourn for those who have no atonement apart from Messiah.
