Our salvation is not just theoretical/doctrine but rather leads to a life that is changed.

We are separated by sin, bought by blood, and united by love.

Salvation is not something that we have earned or can receive on our own, but rather on our own, we have earned separation from God because like the Pharaoh we have set ourselves up as our own god or gods, like the people of Egypt and the Israelites people we seek to satisfy ourselves, control our destiny, and self-preservation. On our own, we are not Holy, and God demands nothing less than the perfect holiness of Himself. Salvation comes through substitution.

Salvation comes through judgment. This theme is constant throughout the storyline of scripture. In this passage, we come to understand that deliverance is not just about freeing people from oppression to the wrongful dictator but likewise about remembering that we are in constant need of being liberated ourselves.
