Holding forth the word of life,.... By which may be meant, either Christ the essential Word, in whom life was, and is, and who is called the quick or living Word, Joh 1:1; and here may be styled the Word of life, because he has all life in him; he has a divine life in him, as God, he is the living God; and it is given to him to have life in himself, as Mediator, for all his people; and he ever lives as man to make intercession for them: and because he is the author of life in every sense, of natural life to all men, of spiritual and eternal life to as many as the Father has given him: or else the Gospel is intended, and the doctrines of it; and which are sometimes called the words of eternal life, and of this life, Joh 6:68; and that because they are a means of quickening dead sinners, they are a savour of life unto life, 2Co 2:16, and the Spirit that giveth life, and of enlivening and comforting living saints; they treat of Christ who is the life; by the Gospel, life and immortality are brought to light; that gives an account of everlasting life; points out Christ as the way to it, shows that meetness for it lies in regenerating grace, and a right unto it is in the righteousness of Christ.
Now this Word of life is held forth, partly by the preaching of it to a dark world, as by some; and partly by professing it publicly, as it should be by all who are enlightened with it; and also by living lives and conversations becoming and suitable to it.
That I may rejoice in the day of Christ. The apostle having observed the advantages that would accrue to themselves, and the benefit they might be of to the men of the world, by regarding the several exhortations he had given them, and which ends he mentions as reasons and arguments to enforce them, closes with taking notice of the use and service it would be to himself; it would give him joy and pleasure when Christ should come a second time to judge the world; and when dead in Christ would be raised, and set at his right hand, and these among the rest, to whom the apostle had been useful; and who continued to bear an honourable testimony in the world to Christ, and his Gospel, to the end:that I have not run in vain, nor laboured in vain; being blessed with such converts under his ministry, as were a credit to religion, an honour to the Gospel, and a crown of rejoicing to him.
