holding forth the word of life; that I may have whereof to glory in the day of Christ, that I did not run in vain neither labor in vain.

as you hold forth the word of life, in order that I may boast on the day of Christ that I did not run or labor in vain.

the word of life holding forth, for rejoicing to me in regard to a day of Christ, that not in vain did I run, nor in vain did I labour;

holding forth [the] word of life, so as to be a boast for me in Christ's day, that I have not run in vain nor laboured in vain.
