Well, Jesus already said what He would do for those who confess Him before men, and I assume we can also assume the converse to be true:
Matthew 10:32
Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.

Yes, the converse is true.
Mark 8:38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
Luke 9:26 For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come in his own glory, and in his Father’s, and of the holy angels.
