Waging Good Warfare
1Tim 1:18 This charge I commit to you, son Timothy, according to the prophecies previously made concerning you, that by them you may wage the good warfare,
What charge? The commands he had given previous in this chapter and those to follow. But as for the prophecies made of Timothy we have no record other than "He was well spoken of by the brethren who were at Lystra and Iconium." Acts 16:2, which apparently influenced Paul to chose him as "a man is valued by what others say of him." Pr 27:21
What does Paul mean when he says, "by them you may wage the good warfare"? By what? By the commands he's giving him. Trying to living the Christian life without having specific commands and instructions in mind is like going into battle without a weapon. In fact the Bible says that the sword of the Spirit is the Word of God - the Bible. (Eph 6:17) Without it we have no commands or instructions by which to wage war. (Though perhaps some Christians find that preferable.)
