I would like to give a biblical example of “babbling like the pagans” and vain repetition. In 1 kings 18:26-29 this is exactly what we see pagans doing. Its an example of pagan babbling and vain repetition. I think this is what our lord is commanding us not to do when he says not to babble like the pagans.
1 kings 18:26-29
26 So they took the bull given them and prepared it.
Then they called on the name of Baal from morning till noon. “Baal, answer us!” they shouted. But there was no response; no one answered. And they danced around the altar they had made.
27 At noon Elijah began to taunt them. “Shout louder!” he said. “Surely he is a god! Perhaps he is deep in thought, or busy, or traveling. Maybe he is sleeping and must be awakened.” 28 So they shouted louder and slashed themselves with swords and spears, as was their custom, until their blood flowed. 29 Midday passed, and they continued their frantic prophesying until the time for the evening sacrifice. But there was no response, no one answered, no one paid attention.
“The prayers of the pagan prophets were “vain” because, after spending the entire day frantically calling upon him, Baal never responded. He wasn’t a real god, unlike the God of Israel, who always answers sincere prayer. Jesus’ point in Matthew 6:7 is that we don’t need to spend all day leaping over altars, cutting ourselves, and raving to get our heavenly Father’s ear. He hears our prayers no matter what type of prayer is offered: lengthy or short, composed or extemporaneous, group or individual, repetitious or unique.” Tl frazier ewtn
