God tells us in His word in 2 Chronicles 7:14

Then if My people who are called by My name will humble themselves and pray and seek My face and turn from their wicked ways, I will hear from heaven and will forgive their sins and restore their land.

The most beautiful thing about this passage is He didn’t say all people or how many people, He just said His people.

He didn’t say certain things would be excluded.  He said He would heal our land and forgive our sins.  There is nothing too big for God.

God is true to His word.  He hears us.  He answers us.  When we pray He meets us where we are.  His presence fills our hearts.  Even when we are all alone the Holy Spirit will join us in prayer so we are never praying alone.  We can ask for anything, even a good grade in school or a restored friendship and He will hear us.  He said anything, no exceptions.

Matthew 18:19

“I also tell you this: If two of you agree here on earth concerning anything you ask, my Father in heaven will do it for you.
