So basically I am going to hell if I smack my thumb with a hammer and shout Jesus fecking christ that hurts!

Or if I go to church and promise not to do it again I am home and dry ?

Are you still a child of God if you are in your 50s ?

Going to Church will no more make you a Christian than dragging your Great Aunt into the CCS will make her a City fan.
A child of God is any Christian, and I mean a Christian by God's definition, not man-made religion.
Hammer or not, your automatic habit (and that of millions of others) of naming one Man's Name in anger from all the numerous religious icons that everyone has heard of (buddha, mohammid, Vishnu, Shiva etc) indicates one thing, the god you serve hates one Man above all others, the One who defeated Him at the Cross; so all his children can't help but use His Name in anger all the time.
