Passage
no one serving as a soldier did entangle himself with the affairs of life, that him who did enlist him he may please;
no one serving as a soldier did entangle himself with the affairs of life, that him who did enlist him he may please;
2 Timothy 2:2 and the things that thou didst hear from me through many witnesses, these things be committing to stedfast men, who shall be sufficient also others to teach;
2 Timothy 2:3 thou, therefore, suffer evil as a good soldier of Jesus Christ;
2 Timothy 2:4 no one serving as a soldier did entangle himself with the affairs of life, that him who did enlist him he may please;
2 Timothy 2:5 and if also any one may strive, he is not crowned, except he may strive lawfully;
2 Timothy 2:6 the labouring husbandman it behoveth first of the fruits to partake;
The verse centers on "serving", "soldier", "entangle", "himself", "affairs", "life", "enlist", and "please". It is saying that the verse draws attention to "serving" and "soldier", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "thou therefore suffer evil as a good..." into verse 5's "and if also any one may strive...", so "serving" and "soldier" 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 "serving" and "soldier" with trust shaped by these words, not by a vague optimism outside the passage.
