We are not to ask such a question as that: “Can God furnish a table in the wilderness? Can He give us bread to eat? Can He provide flesh for His people?” (Psa. 78. 19). This is the question of unbelief, Can God provide supply for my temporal or spiritual necessities? Can He pardon such sins as mine? Can He subdue such corruptions as mine? Can He supply such wants as mine? “How can these things be?” O blasphemous unbelief! What cannot a God of infinite power do? This infidelity hath a mouth full of blasphemy. What answer gave God to this question to Israel? It is said, “The Lord heard this, and was wroth: so a fire was kindled against Jacob, and anger also came up against Israel; because they believed not in God, and trusted not in His salvation.”
