This tattoo design that I found on deviant art is similar to a symbol I'm developing for this site and my book. It incorporates both the biohazard sign and a symbol that can reference the Holy Trinity.
Check out this awesome art!
biohazard ver. 2 by ~blakewise on deviantART
I am intrigued that the biohazard symbol has three circles that are held together within a circle in the center. And yet the circles are all broken. We have the capability to destroy everything on the planet, so we posess the power of death, and yet, we cannot come full circle to re-establish life.
Our capabilities do not match that of the Genesis Project found in Star Trek II. Resurrection, re-birth and creation renewal belong firmly in the grasp of our creative Triune God. Come, let us worship the only One who has the ability to make all things new, even if we should ever destroy it completely.
O come, let us sing to the Lord;
let us make a joyful noise to the rock of our salvation!
Let us come into his presence with thanksgiving;
let us make a joyful noise to him with songs of praise!
For the Lord is a great God,
and a great King above all gods.
In his hand are the depths of the earth;
the heights of the mountains are his also.
The sea is his, for he made it,
and the dry land,
which his hands have formed.
O come, let us worship and bow down,
let us kneel before the Lord, our Maker!
For he is our God,
and we are the people of his pasture,
and the sheep of his hand.
O that today you would listen to his voice!
Do not harden your hearts...
~ Psalm 95:1-8a ~
