The people of God are very prone to the wrong kind of fear, when new difficulties appear to them.
What is the Wrong Kind of Fear?
God’s people are troubled with a fear that is sometimes called “slavish fear.” It arises from various sources, including the misbelief of what God has said, and forgetting what He has said concerning them. It flows also from fixing on His providence [instead of His Word], and putting the worst possible construction on it.
Another source it flows from is despondency of spirit and heartlessness. That weakens their hands in the use of lawful means for bearing their own trial and working for their own deliverance. Their faith and hope and all goes to wrack and ruin. Then there often arises an inclination to follow some unlawful means for deliverance, and even if they do not actually follow it, still the heart is naturally laid open for such a temptation. Ordinarily, complaints are the fruits of slavish fear.
To summarise, slavish fear consists in an atheistical putting of created things in a channel of independency on God, as if the creature could come and go of its own accord without commission from Him. “It is God who comforteth: who art thou that art afraid of a man that shall die, &c.?” (Isaiah 51:12). The truth is, the Lord’s people had forgotten the omnipotent power and sovereignty of God, and thought that mere humans could do with them what they pleased without God. When you are so minded, it is a hundred to one if you don’t attempt to get out from under the trial in some unlawful way.
Why do God’s People Have this Fear?
First, there is the great ignorance of God’s care for His people.
That is the cause of all their slavish fear, and it is what He challenges His people for. “Thou hast feared every day, and hast forgotten me: who art thou that art afraid of a man that shall die?” (Isaiah 51:12–13) We imagine ourselves as standing alone without God. “There feared they, where no fear was.”
The second reason is unbelief.
Thirdly, there is atheism, a growing sin, i.e., when His people think of God as like some creature, and created things like God, as if created things can work what they wish without Him. They put God above the creature in some things, and the creature above Him in some other things.
The fourth reason is, because his people yield to this fear too soon.
