Noah walked with God; he didn't only preach righteousness, he acted it. He went through water and didn't melt. He breasted the current of the popular opinion of his day, scorning alike the hatred and ridicule of the scoffers who mocked at the thought of there being but one way of salvation.
Every true Christian is a soldier - of Christ - a hero 'par excellence'! Braver than the bravest - scorning the soft seductions of peace and her oft-repeated warnings against hardship, disease, danger, and death, whom he counts among his bosom friends.
David - the man after God's own heart - was a man of war and a mighty man of valour. When all Israel were on the run, David faced Goliath - alone... with God - and he but a stripling, and well scolded, too, by his brother for having come to see the battle.
Abraham, a simple farmer, at a word from the Invisible God, marched, with family and stock, through the terrible desert to a distant land to live among a people whose language he could neither speak nor understand! Not bad, that!
The floor of Christendom and elsewhere is littered with wrecks made by old prophets. God won't stand nonsense from any man. Every man has to choose between Christ and Barabbas, and every Christian between God and some old prophet.
Battle is the soldier's vital breath! Peace turns him into a stooping asthmatic. War makes him a whole man again, and gives him the heart, strength, and vigor of a hero.
