Yom Kippur, The Jewish Day of Atonement

According to Old Testament passages, Jewish believers were to participate in the observance of Yom Kippur, known as the Day of Atonement. As of sundown later today, Yom Kippur will commence.
Specific practices on this special day include a 25-hour fast, prayer, abstaining from work, suspending regular activities, withholding the application of makeup, brushing teeth, bathing, and wearing jewelry. The primary focus is to seek the forgiveness that only God can offer.
Our Jewish friends participate with this level of commitment because Yom Kippur is considered the most sacred of feasts and festivals. The focal point is to rely on the high priest to perform specific rituals for the atonement of sin as taught. This annual event began when Aaron (Moses' brother) entered the innermost room of the temple known as the Holy of Holies. This particular ceremony was to be conducted with the utmost respect and reverence. God provided specific instructions on how and when Aaron and future officiating priests would enter this sacred place (Leviticus 16 and 23:27-28).
However, as historical as Yom Kippur is, the actions of that day were temporary. See, these Old Testament practices foreshadowed what was to come.
Hebrews 10:1-5a; 10 explains, "The law is only a shadow of the good things that are coming—not the realities themselves. For this reason, it can never, by the same sacrifices repeated endlessly year after year, make perfect those who draw near to worship. 2 Otherwise, would they not have stopped being offered? For the worshipers would have been cleansed once for all, and would no longer have felt guilty for their sins. 3 But those sacrifices are an annual reminder of sins. 4 It is impossible for the blood of bulls and goats to take away sins. 5 Therefore, when Christ came into the world...10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all."
To God be the glory for the love He has shown us by atoning for our sins through our Lord Jesus Christ. Second Corinthians 5:21 declares this powerful truth: "God made him (Jesus) who had no sin to be sin for us, so that in him we might become the righteousness of God."
