God has provided many evidences of His existence. One of these is the testimony of His creations: The heavens declare the glory of God; and the firmament sheweth his handywork." Have you ever looked in awe at the night sky with its billions of stars? Or studied the intricate details of a leaf or flower? Or marveled at the miracle of a tiny new baby? These beautiful and complex creations didn't come about by chance. They are the creations of God, your Heavenly Father. They can remind you of His existence and of His love for His children. An ancient prophet declared: "All things denote there is a God; yea, even the earth... and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator."
Look around at the world, escape from the man made creations, and enjoy nature. Then spend some time looking around, look at the details. I see God in the sunsets, I love sunsets, and every evening enjoy just soaking them in, seeing all the color changes. Think about the world, space, planets, look at the images of space, see the beauty and color, and multitude of stars. That to me tells me there is a God, everything in our galaxy fitting so perfectly, how Earth is just the right amount away from the sun to provide enough, but not to much heat for our survival. Psalms 19:1 states "The heavens declare the glory of God." Look around and you can tell there is a God. I have experimented with this in my life. I know there is a God and that he loves us.
