Passage
Thou therefore, my child, be strengthened in the grace that is in Christ Jesus.
Thou therefore, my child, be strengthened in the grace that is in Christ Jesus.
2 Timothy 2:1 Thou therefore, my child, be strengthened in the grace that is in Christ Jesus.
2 Timothy 2:2 And the things which thou hast heard from me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.
2 Timothy 2:3 Suffer hardship with [me], as a good soldier of Christ Jesus.
The verse centers on "grace", "thou", "therefore", "child", "strengthened", "christ", and "jesus". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The next verse adds "And the things which thou hast heard...", so "grace" and "thou" should be read forward into that movement. In 2 Timothy context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grace" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
