The logo's main focus is on the church's common name of endearment "BT". And the "T" within the logo also stands as a symbol for the cross, and the "B" serves as "roads"; and thus "all roads leading to the cross". The colors are based on Revelation 14:12.
The members are a commandment keeping church body, and the law in ancient Israel, was always symbolized in "blue". The other color is "crimson red" symbolizing faith in JESUS CHRIST OUR LORD who shed His blood on our behalf. You will then notice two splashes of blood on the right and left side of the circle to symbolize the old sacrificial system on the left, and on the right a symbol of JESUS' blood ending the sacrificial system and solidifying "The new covenant.
