Baptism as a pledge of allegiance
Baptism is (among other things) a public renouncement of one’s former enslavement to Satan and the other spiritual rulers of this present darkness, and a vow of fealty to the enthroned king, Jesus.
What does baptism signify?
Is it membership in the covenant? Or just membership in the covenant community?
Who is baptism for?
Is it for babies? Or believers only? It is for new covenant members— who the Bible explicitly identifies as regenerate believers.
