Faithful is the saying (πιστος ο λογος). Five times in the Pastorals (1. Timothy 1:15; 1. Timothy 3:1; 1. Timothy 4:9; Titus 3:8; 2. Timothy 2:11). It will pay to note carefully πιστισ, πιστευω, πιστος. Same use of πιστος (trustworthy) applied to λογος in Titus 1:9; Revelation 21:5; Revelation 22:6. Here and probably in 2. Timothy 2:11 a definite saying seems to be referred to, possibly a quotation (οτ) of a current saying quite like the Johannine type of teaching. This very phrase (Christ coming into the world) occurs in John 9:37; John 11:27; John 16:28; John 18:37. Paul, of course, had no access to the Johannine writings, but such "sayings" were current among the disciples. There is no formal quotation, but "the whole phrase implies a knowledge of Synoptic and Johannine language" (Lock) as in Luke 5:32; John 12:47.
Acceptation (αποδοχης). Genitive case with αξιος (worthy of). Late word (Polybius, Diod., Jos.) in N.T. only here and 1. Timothy 4:9.
Chief (πρωτος). Not ην (I was), but ειμ (I am). "It is not easy to think of any one but St. Paul as penning these words" (White). In 1. Corinthians 15:9 he had called himself "the least of the apostles" (ελαχιστος των αποστολων). In Ephesians 3:8 he refers to himself as "the less than the least of all saints" (τω ελαχιστοτερω παντων αγιων). On occasion Paul would defend himself as on a par with the twelve apostles (Galatians 2:6-10) and superior to the Judaizers (2. Corinthians 11:5; 2. Corinthians 12:11). It is not mock humility here, but sincere appreciation of the sins of his life (cf. Romans 7:24) as a persecutor of the church of God (Galatians 1:13), of men and even women (Acts 22:4; Acts 26:11). He had sad memories of those days.
