A quick jaunt through chapter 8 of St. Matthew’s gospel yields a few good ejaculatory prayers:
Lord, if you wish, you can make me clean.
Lord, I am not worthy to have you enter under my roof, only say the word and my servant will be healed.
Teacher, I will follow you wherever you go.
Lord, save us! We are perishing!
The next time you have a few seconds free, consider offering up one of these prayers or one of the many, many other prayers from the people that Jesus interacted with in the gospels.
