Akatastasia (G181) is disorder or unstable chaos — the absence of settled arrangement (katastasis). Paul contrasts it with peace: 'God is not a God of confusion [akatastasias] but of peace' (1 Corinthians 14:33). James says wherever jealousy and selfish ambition are found, there is disorder (akatastasia) and every vile practice.
The NT's use of akatastasia reveals a theology of order rooted in God's character. Divine worship, church life, and human relationships are to reflect God's ordered, peaceable nature. Chaos is a sign of where the flesh or demonic is operating. The eschatological vision of the new creation is shalom — perfect ordered peace, the opposite of akatastasia.
