Obviously they believe they are right. Personally I think we are all crazy. Me included. Every single person has an opinion and believe a hundred percent their opinion is right (which we call faith, belief). I’ve never seen so many strong opinions in my life. Maybe I just never noticed when it was opinions over which house to buy, which job, which shirt to where ….Faith, hope, and belief opinions are another story to me. They are as plentiful as the diversity of houses, jobs, and clothing but something different is attached to it.
"Faith is believing what you know ain't so" (Mark Twain).
^to me something about that is all kinds of messed up. Although that is only just another opinion. For example going by Paul’s example of Christ speaking in him, Christ in Paul pointed at “Faith is believing what you know to be so.”
I can’t see Paul changing to one who preaches the faith he once persecuted standing on “Faith is believing what you know ain’t so.”
I think you made some very good observations. And yet:
1 Cor 1:10,
Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and [that] there be no divisions among you; but [that] ye be perfectly joined together in the same mind and in the same judgment.
I wouldn't think God would have written this is if weren't possible to do. Jesus once said that tradition makes the words of God of no effect. There is certainly a lot of tradition in the Christian church today.
Paul went on to explain exactly why there was so much division in the Corinthian church.
1Cor 3:1-3,
1 And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, [even] as unto babes in Christ.
2 I have fed you with milk, and not with meat: for hitherto ye were not able [to bear it], neither yet now are ye able.
3 For ye are yet carnal: for whereas [there is] among you envying, and strife, and divisions, are ye not carnal, and walk as men?
How that must have hurt Paul to say and the Corinthians to hear. Ouch! We are babes?!
1 Cor 2:1-2,
1 And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God.
2 For I determined not to know any thing among you, save Jesus Christ, and him crucified.
It would appear there is more to the gospel than the crucifixion. But what do we see behind virtually every alter or pulpit in Christian churches? A crucifix. But what is there beyond the crucifixion? Paul certainly alludes that there is something there. Furthermore, he suggests that whatever it is, it will go a long way towards ending the carnality and divisions we currently see. In a nutshell, here it is:
1 Cor 2:6-7,
6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought:
7 But we speak the wisdom of God in a mystery, [even] the hidden [wisdom], which God ordained before the world unto our glory:
The word "perfect" in verse 6 is the Greek word "telos" and it doesn't mean we never make mistakes. It simply means that someone has grown up and reached a goal. That can easily be verified by any Bible dictionary. And the word "mystery" in verse 7 is the Greek word "musterion" which better translated as "secret" which also can be verified by any Bible dictionary. A mystery may never be understood but a secret can be understood once it is revealed, and read on to see that this secret has indeed been fully revealed to the Christian church.
The question then is, what is this secret that Paul mentions in verse 7?
Rom 16:25,
Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery (better translated as secret), which was kept secret since the world began,
Here we learn 2 things about this secret, it is the power to establish us and God kept it a secret from the very beginning of the world. But it is now made available for all Christians to fully know and comprehend.
Rom 16:26,
But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
So God kept a secret from the foundation of the world but it is now made manifest or revealed.
Eph 3:1-5,
1 For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,
2 If ye have heard of the dispensation of the grace of God which is given me to you-ward:
3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words,
4 Whereby, when ye read, ye may understand my knowledge in the mystery (again, better translated as secret) of Christ)
5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
Reinforces that which Paul said in Romans 16:25-26.
Now here's something really interesting about this secret:
1 Cor 2:8,
Which (the secret from vs 6 &7) none of the princes of this world knew: for had they known [it], they would not have crucified the Lord of glory.
The princes of this world are none other than the devil and his cohorts. See Ephesians 2:2. Wouldn't you have to wonder why the devil would not have crucified Jesus had he known this secret? Colossians has the answer to that.
Col 1:25-27,
25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God;
26 [Even] the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
27 To whom God would make known what [is] the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:
The upshot of this secret is that all born again Christians have Christ in them. And remember, God was in Christ. So it is God in Christ in you! So instead of keeping track of one Jesus in one place at a time (which was enough of a pain for the devil), he now has to keep track of billions of Christs! The only think he could do was to prevent Christians from knowing about the secret. Without a clear understanding of the power we have because of Christ in a Christian, he can prevent that Christian from fulfilling the promise Jesus made in John.
John 14:12,
Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto my Father.
The devil succeeded in keeping this truth from those in Corinth, and sad to say he is succeeding in much of Christendom today. Hence all the division.
One final thought; please try to avoid deciding for yourself exactly what this secret is. Instead read Paul's epistles and let them tell you what it is. It's all been there for 2,000 years and running. Here's a good book that could help you get started:
