O how uncomely a sight is it to see, a bold sinner and a fearful saint, one resolved to be wicked, and a Christian wavering in his holy course; to see guilt put innocence to flight, and hell keep the field, impudently braving it with displayed banners of open profaneness; [to see] saints hide their colours for shame, or run from them for fear, who should rather wrap themselves in them, and die upon the place, than thus betray the glorious name of God, which is called upon by them to the scorn of the uncircumcised. Take heart therefore, O ye saints, and be strong; your cause is good, God himself espouseth your quarrel, who hath appointed you his own Son, General of the field, called 'the Captain of our salvation,’ Heb. 2:10 . He shall lead you on with courage, and bring you off with honour. He lived and died for you; he will live and die with you; for mercy and tenderness to his soldiers, none like him.
