I was searching for pictures on the Web to illustrate "David Fights Goliath" and found the following:
Is this a good picture? Read 1 Samuel 17:41-51. Does the picture accurately illustrate the story ... the truth? What's wrong with it?
It is unlikely that Goliath was holding a sword. In 1 Samuel 17:51, David took Goliath's sword out of its sheath to cut off his head with it. If Goliath was holding his sword when he fell on his face to the ground then the sword would not be in its sheath! Unless he put the sword back into its sheath as he was falling ... Ha-Ha! Or unless he was holding a sword that was not his.
More likely, he was holding a javelin (1 Samuel 17:6) when he fought David.
Teach the Truth - So it is a javelin and not a sword; what's the big deal? The issue at stake is the truth. As teachers of the Word of God, we have the responsibility to teach it accurately.
Because children may not ask deep theological/intellectual-challenging questions, there is a danger that teachers of children do not exert themselves to study the Word of God. It should not matter whether our audience is adults or children; we must ...
Be diligent to present yourself approved to God
as a workman who does not need to be ashamed,
accurately handling the word of truth.
2 Timothy 2:15
Did I use the above picture? Yes, I did ... to challenge the children to find out what is wrong with it.
