Keep back thy servant also from presumptuous sins; let them not have dominion over me. Psalm 19.13.
From this verse of David’s psalm we are shown that there are two kinds of sin before God: one is the sin of rebellion, the other is that of presumption. Not doing what one is told to do constitutes the sin of rebellion. Now we all know the sinfulness of this kind of sin; and from this sin we wish to be delivered.
But please take note that besides the sin of rebellion there is also that of presumption, which is, that we do what we are not ordered to do. To be active outside of the Lord’s will is to be presumptuous. Do we know that it is equally sinful for us to act without God’s order? It is reckoned as sin before the Lord if we work for Him without His command and instead work according to our own idea, even though we may view what we do to be most excellent.
The prayer of David is for Jehovah to keep him away from presumptuous sin.
