In Matt and Luke it tells us we choose whom we will serve, the God's of our ancestors (religions) or ourselves or the Lord God. The Lord looks upon the heart of a man or woman and knows the intentions behind their choices.
I have a tattoo on my side.because my grandpa used to tell me this "be not afraid". And the phrase "do not be afraid" is written in the bible 365 times. that's a daily reminder from god to live every day being fearless.
