Spontaneous prayer Is when you have a conversation with our Lord: Just talking to God in your own words.
Begin with the Sign of the Cross.
Talk to God using your own Words.
Some Ideas of what to talk bout:
(Thank Him for something.)
(Tell Him what you are greatful for.)
(Ask Him for help.)
(Ask Him for guidance.)
(Ask Him for encouragement.)
(Ask Him for inner strength.)
(Recognize He is with you always.)
End with the Sign of the Cross.
