2Thess 2: 13

(KJV)
But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:

loved by the Lord, because God chose you from the beginning
tc ‡ Several mss (B F G P 0278 33 81 323 1505 1739 1881 al bo) read ἀπαρχήν (aparchēn, “as a firstfruit”; i.e., as the first converts) instead of ἀπ᾿ ἀρχῆς (ap archēs, “from the beginning,” found in א D K L Ψ 1175 1241 Maj it sa), but this seems more likely to be a change by scribes who thought of the early churches in general in this way. But Paul would not be likely to call the Thessalonians “the firstfruits” among his converts. Further, ἀπαρχή (aparchē, “firstfruit”) is a well-worn term in Paul’s letters (Rom 8:23; 11:16; 16:5; 1 Cor 15:20, 23; 16:15), while ἀπ᾿ ἀρχῆς occurs nowhere else in Paul. Scribes might be expected to change the text to the more familiar term. Nevertheless, a decision is difficult (see arguments for ἀπαρχήν in TCGNT 568), and ἀπ᾿ ἀρχῆς must be preferred only slightly.

He called you to this salvation
tn Grk “to which,” referring to the main idea of v. 13.
through our gospel, so that you may possess the glory of our Lord Jesus Christ.
sn That you may possess the glory of our Lord Jesus Christ. For Paul the ultimate stage of salvation is glorification (Rom 8:30).
