How can God hear everyone's prayers at once?
Here's the answer:
God has no limits!
God can hear everyone's prayers at the same time. He is omnipresent, which means He is present everywhere at all times. We can never find a place where God isn't present there and watching us. God isn't like us—He knows everything, can do anything, and is everywhere at once.
God can answer the prayer from a girl in China while comforting you when you're sad. He listens to our praise in church, but He also watches how we act on the playground. God is with us wherever we go, so we can be sure that He is always watching and caring for us.
God knows our thoughts and prayers even before we say them, and He can easily hear everyone's prayers at the same time, even if they're in different languages and places. God isn't far away, even though we can't see Him. He is right here with us, like a friend standing beside us. He listens to our prayers!
"Great is our LORD. His power is mighty. There is no limit to his understanding" (Psalm 147:5).
"LORD, you have seen what is in my heart. You know all about me. You know when I sit down and when I get up. You know what I'm thinking even though you are far away. You know when I go out to work and when I come back home. You know exactly how I live. LORD, even before I speak a word, you know all about it" (Psalm 139:1-4).
"Then listen to him from heaven. It's the place where you live. Forgive him. Deal with him in keeping with everything he does. You know his heart. In fact, you are the only one who knows every human heart" (2 Chronicles 6:30).
