The Lord reminds us in His word, not to be
a shamed to confess him before others.

Mark 8: 37-38  (NKJV)
37  "Or what will a man give in exchange for his soul?
38  "For whatever is ashamed of Me and My words in this
     adulterous and sinful generation, of him the Son of Man
     also will be ashamed when He comes in the glory of His
     Father with the holy angels."
