I remember living through the cold war, and despite Chinese accusations, it was the cold war balance between the American and Russian nuclear arsenals which stove off a ‘hot’ war, for generations.
The Bible contains a lot of history, and it is there as our example to learn from.
Only one person is described in the Bible as “a man after God’s own heart.” Acts 13:22, After removing Saul, he made David their king. God testified concerning him: ‘I have found David son of Jesse, a man after my own heart; he will do everything I want him to do.’”
That man was King David of Israel, who maintained a strong army which dominated the region and prevented invasion of Israel in his lifetime. It provided his son Solomon a peaceful inheritance.
