No longer a slave

The practice of slavery is used as a type of the bondage sinners are in.

Rom 7:14 … I am unspiritual, sold as a slave to sin.

Moses was a type of Jesus and freedom from slavery is a type of freedom from sin that Christ gives.

Gal 3:7 So you are no longer a slave, but a son; and since you are a son, God has made you also an heir.
