8. So that the believer must have his recourse for help and succour here, unto Jesus the Captain of salvation, and must follow him, and fight under his banners, make use of his weapons, which are spiritual; fight according to his counsel and conduct, taking him as a Leader and Commander, and lying open for his orders and instructions, waiting for the motions of his Spirit, and following them; and thus oppose and fight against this deadly enemy, with an eye always on Christ by faith, depending on him for light to the mind, resolution to the will, and grace to the whole soul to stand in the battle, and to withstand all assaults, and never engage in a dispute with this enemy, or any lust or member of this body without Christ the principal, that is, the soul would despair in itself, and be strong in him, and in the power of his might, by faith griping to him, as Head, Captain, and Commander-in-chief, resolving to fight in his strength, and to oppose through the help of his Spirit. 9. And for this cause, the believer would eye the covenant of redemption, the basis of all our hope and consolation, wherein final and full victory is promised to Christ, as Head of the elect, viz. "that he shall bruise the serpent's head;" and so that in him, all his followers and members of his mystical body shall lift up the head, and get full victory at length over both sin and death. Now it is "God that giveth us the victory, through our Lord Jesus Christ," 1 Cor. xv. 57. The believer would also eye by faith the covenant of grace, wherein particularly this same victory is promised to the believer, in and through Jesus, Rom. xvi. 20. "And the God of peace shall bruise Satan under your feet shortly; and sin shall not have dominion over you, for ye are not under the law, but under grace," Rom. vi. 14. The believer, I say, would look out by faith unto, and lay hold on these and the like promises, and thereby get strength conveyed to himself, whereby he may strive lawfully, and fight valiantly, and oppose with courage and resolution.
