“Valiant” soldiers of Christ are those who bear the shield of faith and carry the sword of the Word of God. They are able to “shoot with the bow” of God’s Law, giving the arrow of the gospel its power. This is what makes them skillful in the battle for souls. They have success, not because they trust in themselves, but because they trust in God and cry out to Him in battle. Their strength is in the Lord.
“Brethren, do something; do something, do something! While societies and unions make constitutions, let us win souls. I pray you, be men of action all of you. Get to work and quit yourselves like men. Old Suvarov’s idea of war is mine: ‘Forward and strike! No theory! Attack! Form a column! Charge bayonets! Plunge into the center of the enemy! Our one aim is to win souls; and this we are not to talk about, but do in the power of God!’” Charles Spurgeon
1 Chronicles 5:18 The sons of Reuben, the Gadites, and half the tribe of Manasseh had forty-four thousand seven hundred and sixty valiant men, men able to bear shield and sword, to shoot with the bow, and skillful in war, who went to war.19 They made war with the Hagrites, Jetur, Naphish, and Nodab.20 And they were helped against them, and the Hagrites were delivered into their hand, and all who were with them, for they cried out to God in the battle. He heeded their prayer, because they put their trust in Him.
