AUV(i)
12 For I am suffering these things [See verse 8] for this reason [i.e., because of being a Gospel preacher]. Yet I am not ashamed because I know whom I have believed in [i.e., Jesus], and I am convinced that He is able to guard what I have entrusted to Him [i.e., Paul’s spiritual well-being] until that day [i.e., the day of judgment].
13 You should hold on firmly to the pattern of sound teaching that you have heard from me, while [maintaining your] faith and love in [harmony with] Christ Jesus.
14 [Also] guard that precious treasure [i.e., the Gospel message] which was entrusted to you by the Holy Spirit, who lives in us.
