No Other Doctrine- Part 4:

*Romans 10:14-17 NKJV
How then shall they call on Him in whom they have not believed? 
And how shall they believe in Him of whom they have not heard? 
And how shall they hear without a preacher? 
And how shall they preach unless they are sent?
*As it is written: “How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!” 
But they have not all *obeyed the gospel.
For Isaiah says, “ Lord , who has believed our report?” 
*"So then FAITH comes by HEARING, and HEARING by the word of God."

I Timothy 1:4 NKJV
(4a) "nor give heed to fables and *endless (Endless- Titus 3:9) genealogies, (anything that was not true; or if it was, yet idle, vain, trifling, and unprofitable)
(4b) which cause 
*disputes (Disputes/Questions-1 Timothy 6:4-5; 2 Timothy 2:22) 
rather than 
*godly (Godly-1 Timothy 3:16; 6:3,11) 
edification which is in faith."

4b- 
"which cause disputes rather than godly edification which is in faith."

That which "raises questions," is NOT for edifying; that which gives occasion for "doubtful disputes," pulls down the church rather than builds it up. 

The gospel as delivered by REVELATION and RECEIVED by faith. 
These fables and genealogies address themselves, the apostle says, to the disputatious, "itching curiosity" of "men's minds," NOT to "their faith".

The substance of them is matter of "doubtful disputation," NOT "revealed truth."
-Pulpit commentary

Ephesians 3:2
"Surely you have *HEARD about the administration of God's grace that was *GIVEN to me for you."

Philippians 1:29 NKJV
"For to you it has been *GRANTED on behalf of Christ"

Hebrews 13:9 NKJV
"Do not be carried about with various and strange doctrines. For it is good that the heart be established *BY GRACE, not with foods which have not profited those who have been occupied with them."

This is why there was prophesy (OT) signs and miracles (NT): to demonstrate that the Disciples/Apostles' teaching was indeed The Truth from God.
