Psalms 119:38

Stablish thy word unto thy servant -Confirm it; make it seem firm and true; let not my mind be vacillating or skeptical in regard to thy truth. This seems to be a prayer against the influence of doubt and scepticism; a prayer that doubts might not be suffered to spring up in his mind, and that the objections and difficulties of scepticism might have no place there. There is a class of people whose minds are naturally skeptical and unbelieving, and for such people such a prayer is especially appropriate. For none can it be improper to pray that the word of God may always seem to them to be true; that their minds may never be left to the influence of doubt and unbelief.
