Let me offer this.
Remember the story of Cain and Abel? Cain was a farmer, and gave some of the first fruits of his crop on the altar. Abel killed an animal and gave that as his form of worship. What happened? Cain's sacrifice was rejected by God because it was not according to the manner in which God required.
The "fair-minded" person would cry out, "Injustice! This is not fair!" Why would God reject Cain's sacrifice? Was it not given with the best of intentions? He labored for that crop, planting the seeds, watering them carefully and patiently waited for the seeds to sprout and grow into a plant that produces fruit. Why would a benevolent and loving God reject this man's sacrifice but accept the sacrifice of his brother?
The answer is simple: Abel followed the instructions. God made it known to them both how He wanted sacrifices to be made and left them to choose. Abel chose well and his sacrifice pleased God, while Cain chose poorly and brought him correction. Let's look a little further at God's response.
6 Then the LORD said to Cain, "Why are you angry? Why is your face downcast? 7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it."
(From New International Version)
God didn't respond to Cain with punishment, but correction. He gave Cain an opportunity to correct himself and have his sacrifice be accepted. What a benevolent master!
How did Cain respond? He lured his brother Abel to a field where he killed him and attempted to hide the remains from God.
I ask you, is God unfair or unjust in punishing Cain by casting him out of His presence and cursing the rest of his days? I think not.
In the same way that God required Cain and Abel to worship Him in a very specific manner, He also wants us to worship in a prescribed way.
Now that we have a view of God and his requirements, let us take a look at how different religions describe what our purpose is.
(credit to ReligionFacts for the info.)
There are obviously hundreds more, but I believe the list above will serve us well in our comparative analysis.
Every one of the religions listed above, as well as those not mentioned, believe and teach that their way to live for God and ultimately (for some) spend eternity with Him is THE way. Obviously they are not all the same, while they all teach ultimately that man should be morally good, they are all very different in describing why.
Simple analysis brings me to the conclusion that if all of these teachings are fundamentally different, we must draw one of the following conclusions:
1. They are ALL wrong.
2. One of them is right.
What we can not conclude is that they are ALL correct, because they disagree. God is not a God of confusion, but order, and it goes against His character to write a different prescription of worship for every culture that contradicts the way in which some other culture must worship.
Would God on one hand tell the atheist to ignore Him and depend on man to solve the world's problems, while at the same time tell the Muslim to submit to Him in order to live a good life and get to heaven?
It is important to remember that God created us and owes us nothing, while we owe Him our very lives. He us fully justified in asking what he wants of us, even if it offends us or violates our sensibilities. He is not obligated to us in any way but He is obligated to adhere to His own character and principles. What is exciting is that He gives us access to His thoughts, character, and principles through what He created: nature, the people around us, and the written word.
Most significant of all, and more exciting, is that He came into our history as a man by way of a virgin birth, lived a perfect, sinless life for 33 years, was crucified in spite of His innocence on our behalf, was buried in a tomb for 3 days and rose again to conquer death; again, on behalf of those whom He has no obligation as the creatures of His own creation. I am not talking about the Bible, I am talking about history. I am not talking about religion; I am talking about having a relationship with the one who created us, ultimately fulfilling our purpose for existing.
We are the ones that have fallen away through endless intellectual pontification, by limiting God to what we can understand or conceive, the clay telling the Potter how we must be formed and to what end He must use us. This is the worst form of pride, especially in the face of what He has done in spite of our hearts that have been darkened.
God exists and created us to glorify and worship him. I don't mean worship as in standing in a church holding your hands up singing at the top of your lungs (this is the picture that always pops into my head when that word is spoken), although this is certainly a valid form of worship, but worshipping God with our thoughts, actions, words, conversations, generosity, and the like. He, as the creator, has the right to require that our worship be done in a very specific manner.
Do you desire to worship God in the specific way that He requires? If so, you must search and decide what is the "sacrifice of Cain" and what is the acceptable form of worship, because He is NOT politically correct, nor is He interested in our definition of fairness or worship.
