I am serious about this because I , more then a lot, am aware the debates are going to go on and on about such things as the Trinity, Predestination, Free Will , Baptism, Tripartite man, Hell, and a host of other interesting and not so interesting subjects.
And YES, I will be in the mix.
But most people believe there is a right way to view things or you are wrong. I have run into very few fence sitters on any subject.
So here is my question.
What if you believe you are right and you can back up your beliefs in the Holy Word... as most everyone claims to do, but then comes the day and you find out you have been wrong about things other then having the tremendous Faith in Jesus and what he did for us.
Do you think it will matter in the end?
I think the Scriptures give the answer as to what is the most important duty for humans in their vapor of a life on this earth.
Ecclesiastes speaks about "vanity of vanities" which I believe describes the doctrines and philosophies you are pointing out. The Wisdom of God is not historically received very well by men, they are looked at as "Beggarly Elements" and a "Yoke of Bondage". Ecc. points this out to me.
Ecc. 12:
11 The words of the wise are as goads, (Like A mirror that shows us who we are?) and as nails fastened by the masters of assemblies, which are given from "one shepherd".
12 And further, by these, my son, be admonished: of making "many books" there is no end; and much study is a weariness of the flesh.
Religious men have created and promoted doctrines, philosophies, traditions, religions, web-sites and book after book after book all promoting one religious opinion or perspective over another. To read them all would probably cause brain damage. And why do this when we both have the Oracles of God in our own Homes. Holy scriptures that have remained the same for century after century after century. These "Word's of God" define for us what is clean, what is Holy, what is Just, what is Righteous according to the God and Father of the Lord's Christ. Paul instructs men to trust these Holy Scriptures
"for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works."
Jesus said to "Live by" these Words, and SEEK the Righteousness of God through them.
Of course, for those who believe in Jesus enough to be a "Doer" of His sayings, they would no longer have any use for a Levite Priest, or any corruptible preacher or the religious sect they are promoting. Definitely not good for religious business, and the Pharisees pointed out. We have the Oracles of God in their own homes, and as a result, "We" now sit in Moses seat. We have the Prophets and Jesus and the Apostles God gave Him as their guides and teachers. All we need is belief/faith. The Spirit of Christ which inspired Ecclesiastes makes this point perfectly.
13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man. 14 For God shall bring "every work into judgment", with every secret thing, whether it be good, or whether it be evil.
For me, a nobody for sure, God's works have already been judged as righteousness. If I walk in the Works that God before ordained that I should walk in them, I am safe. His Words and instruction is a refuge for me and my family.
If I want to know what is food, God has set apart an entire chapter to define for me what HE deems as food. As a result, every time I eat, shop for food, or even get hungry, my mind goes to God's Word. It is a refuge for me, and keeps God's Word in my mind throughout the week in this evil world. He defines for me what days HE esteems above other days. Now in the world God placed me in, there are religions that also esteem one day above another. But this isn't the "Work of God", rather, the work of man. I am shown how to treat others, how to engage in just Judgment. I have everything I need
That the man of God may be perfect, throughly furnished unto all good works."
To turn away from Him and seek the advice from some other Author or voice, although very popular as the Ecc. author points out, nevertheless, these only lead to the "works " of man.
What I found, is that when a man "Strives against transgressing God's Commandments" and Judgments, AKA "Sin", when a man "Presses towards the Prize of perfection", that was in Christ Jesus, these theological battles between the religious sects and businesses of this world fade away. They lose their importance because of the biblical fact that turning to God brings about a renewed spirit in men's mind. And the Fear of the Lord is the Beginning of wisdom.
So I believe salvation is completely based on what we "choose" to believe, which is determined by "Who" we choose to listen to, and whose Words we chose to live by.
And in the end, God is always the Right One.
At least I think I can.
