Why do we repeat the same prayers every single say?
Is it really necessary to proclaim that God is One three or four times every day of year?
It’s like when a wife asks her husband why he didn’t say “I love you.” Many men would say “you know I love you, why do I need to keep repeating it?”
The wife would answer “because I like to hear it.”
The words we use in the prayers are what we know God wants to hear. He doesn’t need to be reminded every day that he is one. He needs to hear it from us.
