I end (_Deare Christian_) with the _proposall_ of two _Christian knots_, or _Riddles_, not unsuitable to these present _Times_ and _Spirits_? [Sidenote: Two Christian Riddles, suiting these times and spirits.] _First_, Why is the _Heart_ of a _David_ himself (_Psa. 30._) more apt to decline from _God_, upon the Mountaine of _Joy_, _Deliverance_, _Victory_, _Prosperity_, then in the dark _Vale_ of the shadow of _Death_, _Persecution_, _Sicknesse_, _Adversity_, &c. _Secondly_, Why is it, since _God_ worketh freely in us to _doe_ and to _will_ of his owne good pleasure, that yet he is pleased to command us to _work_ out our owne _Salvation_ with _Feare_ and _Trembling_? Let us all humbly beg the _Finger_ (the Spirit) of the Lord to untie these _Knots_ for us. _I desire to be thine unfeighned in_ Christ Jesus, _R. W._ [Illustration] The _Contents_ of this _Discourse_. _The_ Heads _are three_. _Under the_ first _are contained the_ Arguments _of_ Spirituall Life, _wherein the_ Weakest _and the_ Sickest _Child of_ God _may finde its_ Spirituall Life _apparent, though over-cast and_ eclipsed _with spirituall_ Weaknesse _and_ Distempers. _Under the second_ Head, Arguments _of the strength and_ vigour _of the Spirit of_ Life _and_ Holinesse: _In which the_ strongest _and the_ eldest _in_ Christ, _may find_ Experiments _of Spirituall_ Health, _and Christian_ Activity _and chearfullnesse_. _These_ Experiments _respect_, 1. _The Souls private_ correspondency _with the Lord himselfe_. 2. _Converse and_ correspondency _with_ Men. 3. _Private_ Retirednesses _with it selfe_. _Under the third_ Head _are proposed some_ Means _wherein the_ Spirit _of_ God _usually breatheth for the preserving and maintaining of a truly Spirituall and_ Christian _Health and Chearfullnesse_.
