Everyone who sins is a slave to sin (John 8:34). However, Israel was redeemed from the slavery of Pharaoh, and also from serving other gods (cf. Ezekiel 20:8). Jesus also freed us from our sins by his blood and made us a kingdom, priests to his God and Father
(Revelation 1:5–6). We no longer serve the devil but we serve the Lord Jesus (Philippians 2:9–10).
12 Dieu dit: Je serai avec toi; et ceci sera pour toi le signe que c'est moi qui t'envoie: quand tu auras fait sortir d'Egypte le peuple, vous servirez Dieu sur cette montagne.
