In the Bible, the word vision is more often used as an encounter with God where he imparts special revelation, often intuitively, in dreams, or “in dark sayings.” (Num. 12:6) Sometimes visions can be theophanies, where God speaks directly to the visionary (Num. 12:8).
We don’t necessarily see a direct connection between visions and leadership explicitly taught in Scripture, but we do see a general correlation—most of the main leaders in biblical times were recipients of visions. Others received visions too, but were not leaders (like Isaiah and Jeremiah). But notice that Paul’s qualifications for elders and deacons say nothing about needing to have visions.
