“Means must be used but not relied on (Ps. 44:6). Not to use them is to despise God’s ordinance, but to trust in them is to despise God himself. Man must sow and water; God gives the increase. Man is to bend his bow and sharpen his sword in the day of battle, and use both with his utmost skill; and then trust God as if he were unarmed.” –William S. Plumer “Studies in the Book of Psalms” p. 511 (Banner of Truth).
