1 Timothy 6:4 he is proud, knowing nothing, but is obsessed with disputes and arguments over words, from which come envy, strife, reviling, evil suspicions,
Who is "he" that this verse is talking about? The previous verses show that Paul is talking about men who urge Christians not to submit to authority. There is a connection between envy and rebellion. People who get passed over for a promotion find themselves under the authority of a colleague, and envy develops. Within churches, envy develops when certain people get prominent roles that others feel that they should have.
Submission to authority produces humility, and humility produces grace. Grace gives us the desire and ability to do God's work. Rebellion against authority produces envy and other sins.
