In the early days of the automobile a man’s Model-T Ford stalled in the middle of the road. He couldn’t get it started no matter how hard he cranked nor how much he tried to advance the spark or adjust things under the hood. Just then a chauffeured limousine pulled up behind him, and a wiry, energetic man stepped out from the back seat and offered his assistance. After tinkering for a few moments the stranger said, “Now try it!” Immediately the engine leaped to life. The well-dressed individual then identified himself as Henry Ford. “I designed and built these cars,” he said, “so I know what to do when something goes wrong.” God, as our creator knows how to “fix” us when our lives are broken by sin.
God is not discoverable or demonstrable by purely scientific means, unfortunately for the scientific minded. But that really proves nothing. It simply means that the wrong instruments are being used for the job.
A Sunday School teacher saw one of her little boys drawing furiously with a set of crayons. “What are you doing, Johnny?” she asked. “I’m drawing a picture of God,” said Johnny. “But Johnny,” said the teacher, “nobody knows what God looks like.” Replied Johnny: “Well, they will by the time I’m through with THIS!”
In looking for a challenge or some direction in life, the most challenging task we can approach is the zeal to come to know God. Think how that process might begin with some questions/answers:
Also known as: The Almighty, Jehovah, the Father, Lord.
Occupation: Sustainer and ruler of the universe.
Sex: Does not apply.
Place of birth: Does not apply.
Social Security: None.
Mother’s maiden name: None.
Honors received: Too numerous to list.
God doesn’t fit a mold, does he? He is, to put it mildly, unique. One of a kind. Indescribable, some would say! God is beyond cataloging, and no computer resume, no investigating committee, not even a CIA computer could give an exhaustive profile of who He is and all that He’s done.
God cannot be grasped by the mind. If he could be grasped, he would not be God. Yet we cannot give up! We can’t throw up our hands and dismiss Him as a mystery…we need Him!
Imagine a sheer, steep crag with a projecting edge at the top. Now imagine what a person would probably feel if he put his foot on the edge of this precipice and, looking down into the chasm below, saw no solid footing nor anything to hold on to.
This is what I think the soul experiences when it goes beyond its footing in material things, in its quest for that which has no dimension and which exists from all eternity. For here there is nothing it can take hold of, neither place nor time, neither measure nor anything else; our minds cannot approach it.
And thus the soul, slipping at every point from what cannot be grasped, becomes dizzy and perplexed and returns once again to what is connatural to it, content now to know merely this about God, that it is completely different from the nature of the things that the soul knows. 
It’s amazing in this world the way people respond to God, as they understand Him…it’s very different: some grovel before totems; others bring offerings of chickens and goats; others kneel five times daily to chant prayers; others go into trances. Some believe in God so intensely they preach in foreign lands; others deny His existence by their silence.
We need to come to see God in people around us. We need to know Him in a personal way.
I’m thinking of a little boy named Timmy. Timmy was very afraid of the lightning and the thunder. His mom and dad went into his room during a thunderstorm and said, “Now, Timmy, don’t be afraid. God is right here in the room with you.”
He said, “Okay, Mommy and Daddy, I won’t be afraid.”
But then as the mommy and daddy went into their room and started to get ready for bed, the lightning clapped, and the thunder rolled, and Timmy screamed bloody murder. Timmy’s daddy and mommy went back into the room and said, “Honey, we thought we told you, you don’t need to be afraid. God is right here in the room with you.”
Timmy said, “Mommy and Daddy, I know God is right here in the room with me, but I need someone with skin on.”
