The willing placement of oneself under God-appointed authority for the good of the whole. The Greek hypotasso (to arrange under) is a military term — ordered ranks, each soldier under the next, all under the commander. Scripture commands mutual submission among believers (Eph 5:21: submitting yourselves one to another in the fear of God), wives to husbands (Eph 5:22-24), children to parents (Eph 6:1), servants to masters (Eph 6:5), citizens to magistrates (Rom 13:1; 1 Pet 2:13), younger to elder (1 Pet 5:5), and all Christians to Christ as Head (Eph 5:23-24). The Father-Son submission within the Trinity (1 Cor 11:3; 15:28) is the eternal pattern. Biblical submission is not weakness; it is the active strength of placing one's will under God's ordered authority, knowing the authority is itself accountable to the One who established it. Christ's own submission to the Father in Gethsemane (not my will, but thine, be done) is the highest expression of the virtue.
