[2:5] 1 tn Traditionally this word (μεσίτης, mesith") is rendered “mediator,” but this conveys a wrong impression in contemporary English. Jesus was not a mediator, for example, who worked for compromise between opposing parties. Instead he was the only one able to go between man and God to enable them to have a relationship, but entirely on God’s terms.
[2:6] 3 sn Revealing God’s purpose at his appointed time is a difficult expression without clear connection to the preceding, literally “a testimony at the proper time.” This may allude to testimony about Christ’s atoning work given by Paul and others (as v. 7 mentions). But it seems more likely to identify Christ’s death itself as a testimony to God’s gracious character (as vv. 3-4 describe). This testimony was planned from all eternity, but now has come to light at the time God intended, in the work of Christ. See 2 Tim 1:9-10; Titus 2:11-14; 3:4-7 for similar ideas.
