The name "Jesus" in the New Testament Greek is the equivalent to Joshua in the Old Testament ... Hundreds of Old Testament prophecies concerning the coming of Christ, who will save people from their sins, were written hundreds of years before they were ever seen.  Just a few are: Genesis 3:15, Isaiah 7:14, 9:6, 52:13 - 53:12, Micah 5:2-5, and more.  All were fulfilled in the coming of Jesus Christ - God's gift of Salvation. 

The Sign of the fish is the earliest symbol of Christianity - and it lives on as the symbol of new life in a fallen world.  By displaying this Joshua Fish for your house numbers, mailbox address plaque, or as your garden or yard sign, you are making a statement that you and your family serve the Lord! 

Joshu 24:15  says it best:  "..As for me and my house, we will serve the Lord." 
God's plan is complete, and is available to anyone who believes ...
Isn't it worth it to share your faith with passers-by?

God knows your heart, and as you courageously display this symbol of your faith for your mailbox address plaque or garden or yard sign, you honor Him!
