Jethro, Moses' father-in-law and priest of Midian, visits Moses. Moses tells him of the Israelites' experience in their exodus from Egypt, and how the LORD has saved them.
This is an example of the width of the concept of salvation in the Bible. In this text, salvation means freedom from slavery, safety from enemies and deliverance from hunger and thirst.
In the gospels the greek word for salvation is similarily used when people are healed.
Therefore, being saved is not just being forgiven. The goal of salvation is not purely religious or spiritual. Biblically, it also has to do with physical well-being, peace, security and justice.
And that gives perspective to how Christians today should preach, act, think and relate to people and the world.
