The Greek verb endynamoo means to strengthen, to empower, or to infuse with power โ literally to put power into someone. It is closely related to dynamis (power) and appears in Paul's letters as a key word for divine enablement.
Philippians 4:13 โ 'I can do all things through him who strengthens (endunamounti) me' โ is one of the most quoted verses in the New Testament, and endynamoo is its operative word. This is not general optimism but specific divine infusion of strength for the circumstances at hand. 2 Timothy 2:1 commands Timothy: 'Be strengthened (endynamou) by the grace that is in Christ Jesus.' Ephesians 6:10 exhorts: 'Be strong (endynamousthe) in the Lord and in the strength of his might.' The pattern is consistent: the source of the empowering is always God, Christ, or His grace โ never the believer's own resources. Endynamoo is the word for supernatural strengthening that enables ordinary people to do extraordinary things for the kingdom.
