O LORD, You have searched me and known me! You know when I sit down and when I rise up; You discern my thoughts from afar. You search out my path and my lying down and are acquainted with all my ways. Psalm 139:1-3

Hats off to the engineers of Toyota.

No, I don't mean that sarcastically. These guys have come up with an invention that is absolutely fantastic. I hope I never have to use it, but for those who need it -- well, it's wonderful.

And what have those engineers come up with? It's nothing less than a wheelchair run by a person's brainwaves. Pretty high tech, don't you think? What happens is this: a person's thoughts are read by transmitters and fed into a computer. The computer analyzes and passes on the appropriate command to the wheelchair.

A person who is otherwise unable to move can think the chair forward, backward, left, or right. A command for an emergency stop is given when the navigator puffs his cheeks.

According to the inventors, the computer learns how to read the brain waves of the operator. Within a week the accuracy rate of controlling the wheelchair is about 95 percent.
That's not perfect, but it sure is pretty good.

It is pretty good, and it is also just the beginning. Nobody can guess how far this kind of robotic assistance will go in helping those who have physical challenges.

Yes, Toyota engineers have done a good thing here. Still, as good as it is, it's small potatoes compared to what God has done. Look carefully at the words of the Psalm. God knows us. He is aware when we rise up, and He doesn't need a computer to discern our thoughts. The Lord knows where we're going before we do, and He is fully aware of the path we will travel. God's knowledge of us is complete.

And this also needs to be said. In spite of knowing us as He does, and that knowing includes an awareness of our sinful shortcomings, the Lord still loves us. He has loved us enough to send His Son to redeem us.

Now, for all who believe, the pathway to heaven is open.

THE PRAYER: Dear heavenly Father, You have created us, known us, and loved us. For doing all which was necessary to save us and move us from hell to heaven, we give thanks. In the Name of Jesus we offer our praise. Amen.


In Christ I remain His servant and yours,
