Journaling can also be meditative writing where the writing itself is a prayer.
It is useful for those who find it difficult to focus in prayer. It is like writing a letter to someone you love (Bergan and Schwan, Birth: A Guide for Prayer):
+ Writing a letter to God
+ Writing an imagined conversation between you and God
+ Writing your answers to questions like “what do you want me to do for you?”
Use the journaling feature in the aPrayer app to capture your imagined conversations or your answers.
