In this image of an educational Snap Circuits kit, a small electronic circuit performs the simple function of shining a light bulb.
I think everyone knows that a light bulb can only light up when a complete circuit is formed from the battery, through a switch to the bulb, and finally back to the battery.
Electronics provide us with another interesting property related to current. If you pick any point on a wire on an electric circuit, the sum of currents going into the point and going out of the point all add up to zero. This even works when there are many wires going to the same point.
Oddly in real life, God doesn’t measure all the good things and the bad things a person does to make sure it comes out to zero, or hopefully positive. God looks at the heart. When a person repents and asks for forgiveness, God makes it so a person is totally forgiven.
Our lives can be so complicated we don’t know what is coming or going. But God makes it easy when we truly repent and walk humbly with him.
