This was my very first tattoo done about three weeks ago! It is an anchor which was a symbol of christianity in biblical times. Underneath it, "agape" is written in greek. Agape is one of the loves from the bible that is perfect, unconditional, pure, etc; like the love God has for us. I decided to put it on my foot as to show my faith in God keeps me grounded and secure.
Love it! I have an anchor with a heart on my left foot for a similar reason, to symbolize faith, hope and love. Also, to remind me that even when times get tough, I refuse to sink.
