Passage
That good thing which was committed unto [thee] guard through the Holy Spirit which dwelleth in us.
That good thing which was committed unto [thee] guard through the Holy Spirit which dwelleth in us.
2 Timothy 1:12 For which cause I suffer also these things: yet I am not ashamed; for I know him whom I have believed, and I am persuaded that he is able to guard that which I have committed unto him against that day.
2 Timothy 1:13 Hold the pattern of sound words which thou hast heard from me, in faith and love which is in Christ Jesus.
2 Timothy 1:14 That good thing which was committed unto [thee] guard through the Holy Spirit which dwelleth in us.
2 Timothy 1:15 This thou knowest, that all that are in Asia turned away from me; of whom are Phygelus and Hermogenes.
2 Timothy 1:16 The Lord grant mercy unto the house of Onesiphorus: for he oft refreshed me, and was not ashamed of my chain;
The verse centers on "Spirit", "good", "committed", "thee", "guard", "through", "holy", and "dwelleth". It is saying that the verse draws attention to "Spirit" and "good", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Hold the pattern of sound words which..." into verse 15's "This thou knowest that all that are...", so "Spirit" and "good" belong inside that flow. In 2 Timothy context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "good" with trust shaped by these words, not by a vague optimism outside the passage.
