Why does God perform miracles?

Today in my Bible I read this little side note devotion and it prompted me to begin writing something I will share soon...

"I wish God would do more miracles in my life. Why don't amazing things happen more often?"
Ever wondered this? Miracles and "amazing things" are great. Still, the best miracle God could ever perform in any life is the miracle of salvation.
Maybe the real question is, What kind of miracles do you want God to do in your life? ...(several examples listed)... Perform some healing to "prove" he's there? If so, you'll be disappointed. He doesn't "perform" just to prove he exists. He would rather that people have faith in what the Bible says about him (that he, in fact, exists).
God promised his followers that he would perform wonderful things through them. And you'll find that the most exciting miracles are when God uses you to lead someone else to him. Those miracles are better; they lead to something eternal!
So ask God to use you to perform the greatest miracle of all- to lead someone to Christ.
