Leviticus 27:12 (NIV)
12 ...Whatever value the priest then sets, that is what it will be.
During Moses' time, people would occasionally make vows to dedicate a person, an animal, or real estate to God. Instead of actually releasing that person, animal or real estate to the priests, that person could keep the person, animal or real estate for themselves and instead pay an equivalent price to the priests. But what should that price be?
Leviticus 27:1-15 sets out the price to be paid for a person, animal or real estate. Notice who sets the price. Whether we're talking about measuring the value of a person (v8), an animal (v12), or a house (v14), it's the priest who has the final say on how much that person, animal or house is worth.
In the same way, your worth was decided by a priest. Your worth was determined when Jesus Christ, our Great High Priest (Hebrews 4:14), died on the cross to save you from your sins. In other words, in the eyes of your Great High Priest Jesus Christ, your life was worth more to Him than even His own.
Because Jesus your great high priest paid the highest price for you, you can know that you are of incredible worth in God's sight. So don't ever let anything or anyone question your worth.
