I use Father or Almighty God, but I always use a name, like Jehova,(prounounced hay-o-bah) in Spanish or the American rendering of the word. I like to think Spanish was around longer, maybe even some version of it was around in the days of Aramaic, although I think Aramaic was widely used. I like Father as my relationship with my own father has been separated from my heavenly Father thankfully.
Absolutely Amen, although I do get weird'ed out sometimes in personal prayer and using amen. I pray, I supplicate, so when I finish the prayer, I request it to be done. It feels redundant to the OCD in me... sigh. I will still use it regularly, and be uncomfortable until recovery helps me understand that too.
Thanks Phoenix, good points.
