1 Corinthians 6:19-20 ESV
Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.
Mixed Costs = Fixed Costs + Variable Costs
This formula is used in Managerial Accounting most often in a manufacturing setting to calculate how much costs a corporation incurs. It’s useful for financial budgeting and creating internal reports.
It’s known algebraically as…
Y = a + bx
Where
Y: Total
a: Fixed Expenses
b: Variable Expenses
x: Units
This is similar to the slope formula from Microeconomics, y = mx + b, just in a different form. Otherwise calculated as rise / run, y2 – y1 / x2 – x1.
Universal Salvation is like a Mixed Cost, where the Fixed Cost represents the fact that everyone will be saved and the Variable Cost shows that people will be saved at different times.
Fixed Cost:
Psalms 112:7
He shall not be afraid of evil tidings: his heart is fixed, trusting in the LORD.
Psalms 108:1
(A Song or Psalm of David.) O God, my heart is fixed; I will sing and give praise, even with my glory.
Ex: When you pay for the fixed monthly rent for factory space, you will be paying the same amount at the beginning of every month.
Fixed means unchanging. The ways of the Lord are unchanging, they are always good! Everyone will be saved, no matter what, that is a fixed fact! It cannot be changed, because it is God’s will and the Lord stays fixed in goodness.
Variable Cost:
Everyone will be saved by believing in faith alone through Jesus Christ. But, the time at which someone personally chooses to trust in Christ Jesus, our Lord and Saviour, is their decision. For some, they may realize the truth early on in their lives. For others, they may realize the truth later on.
Luke 4:40
At sunset, the people brought to Jesus all who had various kinds of sickness, and laying His hands on each one, He healed them.
Being in sin is a sickness. After all, you can’t spell sickness without sin! But, when Jesus was on Earth healing those afflicted with diseases, He did not heal them all at once. He would go from one to the other, healing them on different days, at different times.
It's the same thing with salvation. Christ waits and the time in which someone lets Him into their lives varies.
Hebrews 2:4
God also testified to it by signs, wonders and various miracles, and by gifts of the Holy Spirit distributed according to His will.
The time at which someone is saved and realizes the truth is done according to His will. For some people, the Sovereign Lord may choose to reveal the truth early on, for others, He may wait until later.
Mixed Cost
A good example is the Parable of the Workers in the Vineyard.
Matthew 20: 9-9The workers who were hired about five in the afternoon came and each received a denarius. 10 So when those came who were hired first, they expected to receive more. But each one of them also received a denarius. 11 When they received it, they began to grumble against the landowner. 12 ‘These who were hired last worked only one hour,’ they said, ‘and you have made them equal to us who have borne the burden of the work and the heat of the day
Those who are saved when they are young and those who are saved when they are old are both equally saved. That is fixed. The time when they are saved is variable. Thus, mixed. Universal Salvation is always fixed.
