I Am well assured , that I can add nothing by way of Answer , concerning the Question proposed , to what you are already experimentally acquainted with ; however , to satisfie your desire , and in regard God can make old things new unto us , by giving us a new taste and favour of them , I shall say something .

I must premise , that I remember not that Epithite of Trust any where expresly to occurr in Scripture , onely in Psal . 37. 5. our English Meeter useth it . But however , the same thing we meet with in Scripture , though in other terms : For perfect Trust can import onely two things ; 1. The Truth of it for kind , as a perfect man is a sincere and upright man ; 2. The Strength of it for degree , and so it notes not absolute perfection , but an eminent and singular measure of that grace , above what many , or possibly most attain unto ; and this the Scripture expresseth by Trusting in the Lord with all the heart , Prov. 3. 5. that is , truly and strongly . Such an eminent measure of this Grace , no doubt , had Hezekiah , in respect of which , as well as of other Graces , 't is said of him , that after him was none like him among all the Kings of Judah , nor any that went before him . 2 Kin . 18. 5. But when all is done , the most perfect Trust attainable by us here , is mingled with much Distrust ; which yet doth not deprive us of the benefit thereof , otherwise our condition were sad : Though we believe not , God is faithfull , 2 Tim . 2 , 13. that is , though our Faith be weak , though it often fail , and be at a loss , as to the actings of it ; yet being true , God it by promise obliged , and cannot deny himself : And so though we trust not , not so firmly , not so constantly as we should ; yet where there is any measure of that grace in truth , God is faithfull : and yet it must be granted , that the greater measure of Faith and trust we can attain , the more we may expect from God . According to our faith ( and so according to our trust ) so be it unto you , is his language to us ; we impair and lessen our Mercies by the weakness of our Faith and Trust , as Barak did , Judg . 4. 9. but an eminent Trust and strong Confidence in God , never fails of some eminent appearance of God for us , according to the proportion and measure of our reliance on him .

Now our Trust may be known to be right ,

1. From its Foundation , which is some word or promise of God , Psal . 119. 42. and that rightly understood and applied , else it is a presumptuous confidence without warrant .

2. From the Descriptions of the nature of it , which is excellently represented unto us in variety of significant expressions : 't is described by relying on the Lord , 2 Chron . 13. 18. by resting on him , 2 Chron . 14. 11. by staying our selves on him , Isa . 50. 11. by leaning on him , Cant . 8. 5. by casting our selves , our cares , our burdens on him , Psal . 55. 22. 1 Pet . 5. 7. by having our eyes on him , 2 Chron . 20. 12. and all our expectations from him , Psal . 62. 5.

3. It may be known by the inseparable Concomitants of it , which are , 1. A disclaiming and renouncing of all other props and supports , Prov. 3. 5. Hos . 14. 3. Psal . 20. 7. Psal . 2. 5 , 6. 2. Frequent recourse to him in every exigency . A man will be often running to a faithfull Friend in whom he trusteth , in reference to any business of importance ; he shall be often consulted with , his assistance often implored , upon occasion of every emergent difficulty . So if God be our strong Tower , in every danger we will be running into it for safety , Prov. 18. 10. If our trust be in him , we will be addressing our selves to him , be acknowledging him in all our ways , Prov. 3. 5. Committing our works and affairs to him , Psal . 37. and pouring out our hearts before him at all times , Psal . 62. 8. 3. Trust in God is accompanied with a Care to please him : No prudent man will provoke him , on whom his trust and dependance is for any thing which he valueth ; nor can he have any good ground of confidence in his help and assistance , whom by his daily affronts and miscarriages he makes his Enemy . He that hath friends , must carry himself friendly , Prov. 18. 24. and so must he that will have them for the future , or else in reason he cannot expect to have them long . Hence trust in the Lord and doing good are linked together , Psal . 37. 3. This will greatly strengthen our trust , Prov. 14. 26. and without this all our confidence is vain , Jer . 7. 4 , 5 , &c. 4. True trust in God is attended with the diligent use of such lawfull means as Gods providence offers . Thus Paul so trusts in Gods promise for saving himself and the rest in the ship , as he no way opposeth the use of such means , by which the Providence of God was to be served , Act. 27. Neglect of Means makes our Confidence no other then a presumptuous tempting of God . 5. True Trust in God is accompanied with a sense and bewailing of , and a mourning under our Distrust , together with a striving against it , and a stirring up our selves to hope in God . So David , Psal . 42. 5. Why art thou cast down , why art thou disquieted , O my soul ? still hope in God , &c. And the man in the Gospel , Lord , I believe , help thou my unbelief . So , Lord , I trust in thee , help thou my distrust . 6. 't is accompanied with a sense of our unworthiness of whatever favour or relief we are trusting in God for . So Jacob , Gen. 32. manifesting his trust in God by his recourse to him in his distress , acknowledgeth himself unworthy of all the mercy and truth which God had formerly shewed him , and consequently much more of that protection against Esau , which he further begged of him .

4. This holy Trust in God may be discerned by the Effects of it , which are such as these : 1. It quiets the heart , composeth the spirit , and frees it from distracting fears and cares , at least according to the measure of it , and at such times when the actings of it are not by temptations or otherwise obstructed . Isa . 26. 3. Thou wilt keep him in perfect peace , &c. 2. It holds up the heart , and keeps from sinking , yea , sometimes fills with joy and holy triumph , even when all outward means fail , Hab . 3. 16 , 17 , 18. Though the fig-tree shall not blossome , &c. yet I will rejoyce in the Lord , &c. 3. It enables and strengthens the soul to wait Gods season for Deliverance , yea , though he should seem long to hold us in expectation . Isa . 28. 16. He that believeth , and so he that trusteth in God with all his heart , will not make haste . 4. It effectually preserveth from making use of any unlawfull means . He that trusteth in the Lord needs not do it , for he knoweth whom he hath trusted , even one who knows how to deliver , 2 Pet . 2. 9. and never fails those who trust in him , Psal . 9. 10. To reach forth the hand to take hold of any unwarrantable relief , were to renounce his trust in God ; wherefore in this sence also , he that believeth or trusteth , will not make haste , as that place is likewise understood . 5. Sound Trust in God will make us willing , and in some measure enable us to referr all to his good pleasure , to give up all to his disposal , to put all our all into his hands . And thus much is implied in the phrase of committing our way to him , Psal . 37. 5. When we entirely trust a wise and faithfull man in any weighty business , we referr all to his Wisdom , Care , and Integrity . They who can thus trust God , do as it were engage him in point of Honour not to fail them : And indeed , it is impossible he should fail them , not onely on this account , but likewise upon another , to wit , that he himself hath caused them to trust in him , as the phrase of the Psalmist is , Psal . 119. 49. 1. By Promises to those who shall trust in him ; 2. By Commands and peremptory charges laid on them to do it ; 3. By manifold Experiences of his never failing their expectations formerly ; and 4ly , By most sweet and efficacious Encouragings and drawings of his own Spirit , he hath induced them , and prevailed with them to trust in him : and after all this can he fail them , or betray them ? The Philosophers good nature would not deliver the poor Bird to the Hawk , from which it had taken shelter under his Cloak , and yet he never allured the Bird into that refuge : God hath allured us to take Sanctuary under his Wing , and therefore Heaven and Earth can sooner pass away , then he fail us . How well also he takes it at our hands that we will trust in him , and the security he hath thereupon given us , that one excellent place , Psal . 91. 14 , 15 , 16. abundantly manifesteth .
