This noun refers to the process of preparing or equipping someone for a task, related to the verb for mending nets or perfecting disciples. Ephesians 4:12 describes Christ's gifts of apostles, prophets, evangelists, pastors, and teachers given 'for the equipping of the saints for the work of ministry.' The accusative indicates purpose—these leaders exist to prepare God's people for service. Classical usage shows preparation, furnishing, or training. The word implies bringing people to readiness and competence. Paul's vision sees ministry as the calling of all believers, with leaders functioning as equippers rather than performers.
