Sacrifice
Christians fast as a sign of penance and sacrifice, but are not required to do so
For Christians it is a matter of faith that Jesus is a sign from God, but to others there is no perceivable sign to tell them this. For them, Jesus is simply a holy man or preacher who may have lived around two thousand years ago. They have no need to worship Jesus merely because Christians tell them they should.
Christians make the sign of the cross before prayer as a way to symbolize their faith in the Holy Trinity - God the Father, Son, and Holy Spirit. It is a gesture of reverence and a reminder of the sacrifice of Jesus on the cross.

The most famous secret sign in early Christianity was the Ichtys sometimes spelled ikhthus that resembles a fish and is today known as the Jesus fish.

In the biblical account of the Exodus, it was the Israelites who painted blood on their doorposts during Passover. This act was instructed by God through Moses as a sign for the angel of death to "pass over" their homes and spare them from the tenth plague in Egypt. The blood was to be from a lamb, symbolizing sacrifice and protection. This event is commemorated in the Jewish holiday of Passover.
The symbol of a fish is associated with Jesus because the Greek word for fish, "ichthys," is an acronym for "Jesus Christ, Son of God, Savior." This symbol was used by early Christians as a secret sign of their faith during times of persecution.
