In charging Timothy to “preach the Word,” the Apostle does not mean, as some have supposed, that the pastor should draw his sermon material equally from all parts of the Bible. True, “all Scripture” is given so that the “man of God” may be fully equipped for his ministry. But in this same letter the Apostle Paul indicates that the Scriptures must be “rightly divided” (II Tim. 2:15) and that his own God-given message is the Word of God in particular for the present dispensation of grace (See II Tim. 1:7-14; 2:7-9). Thus the Apostle declares by inspiration that believers are established by “my gospel and the preaching of Jesus Christ according to the revelation of the mystery” (Rom. 16:25).
How often the Apostle insists that his message is the Word of God! To the Thessalonian believers he writes with joy:
“For this cause also thank we God without ceasing, because, when ye received the Word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the Word of God…” (I Thes. 2:13).
Thus the Apostle writes to Timothy, in this his last letter:
“Hold fast the form of sound words which thou hast heard of me…” (II Tim. 1:13).
“And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men…” (II Tim. 2:2).
“Remember that Jesus Christ, of the seed of David, was raised from the dead according to my gospel” (II Tim. 2:8).
The charge to “preach the Word,” therefore, refers to “all Scripture” in general, but to Paul’s God-given message in particular. This is obvious, for it is in urging Timothy to faithfully carry on in his place that the Apostle charges him to “preach the Word.” source
