How few know about Paul, God’s apostle to the nations!
Not Matthew, or Mark or Luke; not Peter or James or John, but Paul alone wrote:
“FOR I SPEAK TO YOU GENTILES (or, YOU OF THE NATIONS] INASMUCH AS I AM THE APOSTLE OF THE GENTILES [NATIONS]: I MAGNIFY MINE OFFICE” (Rom. 11:13).
And remember, Paul wrote this by divine inspiration. But note well that Paul did not magnify himself, but his office, to which he had been appointed by the glorified Lord. In defending his apostleship before the Galatians, he wrote:
“But I certify you, brethren, that the gospel which was preached of me is not after man.
“For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ” (Gal. 1:11,12).
In many other passages the Apostle claims to speak as a direct representative of Christ (See I Cor. 11:23; 15:3; Eph. 3:2,3; I Thes. 4:15; etc.). To Timothy Paul wrote in I Tim. 6:3-5 concerning his own writings:
“If any man teach OTHERWISE, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness, he is proud, knowing nothing…”
This could not demonstrate more emphatically Paul’s claim that his words were “the words of our Lord Jesus Christ,” received from Him by direct revelation. To the Corinthians, who questioned this, the Apostle wrote:
“…IF I COME AGAIN I WILL NOT SPARE, SINCE YE SEEK A PROOF OF CHRIST SPEAKING IN ME” (II Cor. 13:2,3).
The proof of this claim? This was overwhelming indeed, for Paul was used more than any other apostle to found churches and lead men into the knowledge and joy of salvation. To the Corinthian believers he wrote what he could have written to many thousands of others: “The seal of mine apostleship are ye in the Lord” (I Cor. 9:2). source
[…] The Apostle Paul had opposition from without and from within the company of believers, and had much to be discouraged about, but he didn’t quit. His testimony was: “seeing we have this ministry…we faint not” (II Cor. 4:1). He kept his heart focused on serving the Savior, with Galatians 6:9 in mind: “And let us not be weary in well doing: for in due season we shall reap, if we faint not.” Simply put, heaven and reward from the Savior strengthened the resolve of this servant. It can for us too. […]
