What - or Who - should we trust?

Some trust in wagons and some in horses.But we will trust in the name of the Lord, our God. (Psalm 20:7, New LifeVersion)
Last spring, I bought a newer vehicle. It has a ton ofsafety features, all of which blow my mind. It tells me if I veer from my laneand when someone moves into my blind spot. It yells at me if another carapproaches me when I'm backing up. How can a vehicle know all that ishappening?
Of course, it also has a light that comes on when Ihave a low tire – a feature my last three cars have had. Unfortunately, thelight didn't go off even after Hubby put air in the tire. Hmm? How trustworthyis that?
Or, actually, how much should I trust all these otherfeatures? If I pull over in front of someone because one of those lights didn'tcome on, who's liable? The manufacturer? They put enough trust inall these safety features that my car insurance is lower because they believethe chances of me having an accident are lower.
But what – or who – can we trust 100% of the time? Whowarns us every time we stray into the other lane? Whose lights always come on whenthere is the need to be cautious?
God is the only One we can trust with everything, allof the time. As long as we put our faith in Him, He will not let us wander. Hewill keep us from harm.
