Hank, thank you for this refreshingly polite post!
Beginning with Judges 14:6, the Bible (not David talking to Saul) tells us repeatedly of Samson’s great and supernatural strength and of the exploits that he accomplished using his great strength. The Bible tells absolutely nothing of the sort about David. But some will ask, “How about the tens of thousands of men that the Bible says that David killed?” The answer is that the Bible does not say that David killed thousands of men, the Bible says,
1 Sam. 29:5. Is this not David, of whom they sing to one another in dances,
“Saul has killed his thousands,
and David his ten thousands’?” (NRSV)
The Bible does not say that the words in this song were true, and we have no biblical accounts that document the accuracy of the words in this song. Indeed, the Bible portrays David’s physical strength and abilities of that of an average man—or even less! Most certainly Saul was not impressed by David’s stature! Therefore, the Bible neither says nor implies that David had the ability to catch lions and bears by the jaws, strike them down, and kill them, and one would be very hard pressed to prove that any man is anatomically and physiologically cable of such a feat. The reasonable and fair conclusion is that David lied to Saul.
However, all of this is irrelevant to the issue of Christians taking a gun with them when they go to church because Christians live under a covenant with God that is vastly different from the covenant under which David, Samson, Joshua, and Caleb lived. The behavior that was acceptable and even commanded under to Old Covenant was hugely different from the behavior that is acceptable and even commanded under to New Covenant.
For those persons living under the old covenant we read,
Numbers 31:17. “Now therefore, kill every male among the little ones, and kill every woman who has known man intimately.”
Deut. 2:33. “The LORD our God delivered him over to us, and we defeated him with his sons and all his people.
34. “So we captured all his cities at that time and utterly destroyed the men, women and children of every city. We left no survivor.”
Psalms 137:9. How blessed will be the one who seizes and dashes your little ones Against the rock.
Isa. 13:9. Behold, the day of the LORD is coming, Cruel, with fury and burning anger, To make the land a desolation; And He will exterminate its sinners from it.10. For the stars of heaven and their constellations Will not flash forth their light; The sun will be dark when it rises And the moon will not shed its light.11. Thus I will punish the world for its evil And the wicked for their iniquity; I will also put an end to the arrogance of the proud And abase the haughtiness of the ruthless.12. I will make mortal man scarcer than pure gold And mankind than the gold of Ophir.13. Therefore I will make the heavens tremble, And the earth will be shaken from its place At the fury of the LORD of hosts In the day of His burning anger.14. And it will be that like a hunted gazelle, Or like sheep with none to gather them, They will each turn to his own people, And each one flee to his own land.15. Anyone who is found will be thrust through, And anyone who is captured will fall by the sword.16. Their little ones also will be dashed to pieces Before their eyes; Their houses will be plundered And their wives ravished.17. Behold, I am going to stir up the Medes against them, Who will not value silver or take pleasure in gold.18. And their bows will mow down the young men, They will not even have compassion on the fruit of the womb, Nor will their eye pity children. (NASB, 1995)
Zechariah 13:7. “Awake, O sword, against My Shepherd, And against the man, My Associate,” Declares the LORD of hosts. “Strike the Shepherd that the sheep may be scattered; And I will turn My hand against the little ones.”
For those persons living under the old covenant we read,
4. “I say to you, My friends, do not be afraid of those who kill the body and after that have no more that they can do.
5. “But I will warn you whom to fear: fear the One who, after He has killed, has authority to cast into hell; yes, I tell you, fear Him!
6. “Are not five sparrows sold for two cents? Yet not one of them is forgotten before God.
7. “Indeed, the very hairs of your head are all numbered. Do not fear; you are more valuable than many sparrows.
8. “And I say to you, everyone who confesses Me before men, the Son of Man will confess him also before the angels of God;
9. but he who denies Me before men will be denied before the angels of God.”
