There is an amusing story in 1 Kings 18. Elijah has challenged the prophets of Baal to call upon their god and he would call upon the Lord and they would see who answers. As the prophets of Baal call, they become more desperate, even cutting themselves to get Baal's attention.
Elijah taunts them, telling them to yell louder because maybe their god is asleep or away. When Elijah called upon the Lord, God answered immediately by bringing down fire from heaven that not only consumed the sacrifice but the stones of the altar as well.
Sometimes it feels as if God is far away from us and that he doesn't hear our prayers. This is not the case however. God is always near us and always hears our prayers. We do not need to worry about whether God heard us or if He is away because God is always with us.
Idols made with human hands take on human weaknesses. They cannot hear everything and are not always near. But the God who created us is greater than anything that we make in our own image. God is always near and will always hear and answer our prayers.
