There's something about our Christian culture today. We read of in the Bible of all the amazing miracles, all the stories and we say wow, that's so cool. Then when we think of prayer, we think yeah, prayer is good, but seeing God stop the rain, or heal a friend is so much cooler.
We downplay prayer. Its become so ritualistic we pray like we're tying our shoes, only out of necessity. Only because we're expected to. Don't they teach in sunday school you should always pray before you to to bed?
There is enormous power in prayer. And I bet most major acts of God, if not all where preceded by prayers poured out of people's hearts, til there was nothing left to pour out, like wringing all the water out of a washcloth.
How bout when God led the Israelites out of Egypt? Nope we say, pretty sure God did that all by Himself.
The Lord said, "I have indeed seen the misery of my people in Egypt. I have heard them crying out because of their slave drivers, and I am concerned for their suffering." Exodus 3:7
Prayer moves things in the spiritual realm. BIG THINGS. I encourage you to look through the Bible, and look at big things that happened and look before and I bet you will find either prayer or an allegory that to me says they prayed. Here's three examples to look at
Nehemiah 1-2:9, 4:7-9
Acts 1:14, Acts 2
Prayer is indeed the most I can do, because through prayer I'm calling on Him who does all things.
