Yes, the saints are to have peace. This is peace with earthly enemies, with mysterious evils, and with little annoyances. Any of these might keep us from lying down, but none of them shall do so.
The Lord will quite destroy those things which threaten his people; 'I will break the bow and the sword and the battle out of the earth.' Peace will be profound indeed when all the instruments of disquiet are broken to pieces.
With this peace will come rest. 'So he giveth his beloved sleep.' Fully supplied and divinely quieted, believers lie down in calm repose.
This rest will be a safe one. It is one thing to lie down, but quite another 'to lie down safely'. We are brought to the land of promise, the house of the Father, the chamber of love, and the bosom of Christ; surely we may now 'lie down safely'.
It is safer for a believer to lie down in peace than to sit up and worry.
This is something from Charles Haddon Spurgeon's Cheque Book of the Bank of Faith (for all those Canadians who read my blog, note the correct spelling of cheque. XD). It's a lil bitty book that I just started a bit ago, thus only being on January 4th.
