2 Timothy 1:9

ἡμᾶς. Primarily in reference to Paul and Timothy, but true generally.

σώσαντος. For the act of σωτηρία as applied to God, see on 1 Timothy 1:1.

καὶ καλέσαντος κλήσει ἁγία. This calling or vocation is always ascribed by Paul to God the Father; cp. Romans 11:29; 1 Corinthians 1:9; Galatians 1:6 and especially Romans 8:28, τοῖς κατὰ πρόθεσιν κλητοῖς οὖσιν.

οὐ κατὰ τὰ ἔργα ἡμῶν. Cp. Titus 3:5; a distinctively Pauline idea, and important here as balancing the emphasis laid on good works in the Pastorals. see on 1 Timothy 2:10.

ἰδίαν, emphatic, as marking the freedom of the Divine purpose.

ἐν Χρ. Ἰη., in, [not ‘through’], His person.

πρὸ χρόνων αἰωνίων. See Romans 16:25 and Titus 1:2. The grace of Christ, Incarnate, Crucified, Risen, is part of the eternal purpose of God for man, and since time does not limit the Deity, that which is unfalteringly purposed is described as actually given.
