II. To prove that this privilege is attainable in this present life; and that it may appear to be so, let it be considered, 1. That if the knowledge of other things which are of less importance, be attainable, then certainly it is possible for us to attain that which is of the greatest importance. This argument is founded on the goodness of God; if he has given us sufficient means to lead us into the knowledge of other things, which respect our comfort and happiness in this world; has he left us altogether destitute of those means whereby we may conclude, that it shall go well with us in a better? God has sometimes been pleased to favour his people with some intimations concerning the blessings of common providence, which they might expect for their encouragement, under the trials and difficulties which they were to meet with in the world; and our Saviour encourages his disciples to expect, that notwithstanding their present destitute circumstances, as to outward things; yet their _Father_, who _knows that they had need of them_, would supply their wants; and therefore they had no reason to be over-solicitous in _taking thought what they should eat and drink, and wherewithal they should be clothed_, Matt. vi. 31, 32. and if God, that he may encourage the faith of his people, gives them assurance that _no temptation shall befal them, but what is common to men_; or, that they shall not be pressed down, so as to sink and despair of help from him, under the burdens and difficulties that, in the course of his providence, he lays on them; I say, if God is pleased to give such intimations to his people, with respect to their condition in this world, that they may be assured that it shall go well with them, as to many things that concern their outward circumstances therein; may we not conclude from hence, that the assurance of those things that concern their everlasting salvation may be attained? or, if the promises that respect the one may be depended on so as to afford relief against all doubts and fears that may arise from our present circumstances in the world; may we not, with as good reason, suppose, that the promises which respect the other, to wit, the carrying on and perfecting the work of grace, afford equal matter of encouragement; and consequently, that the one is as much to be depended on, as the other; so that as the apostle says, they who have fled for refuge, to lay hold on the hope set before them, may have strong consolation arising from thence, Heb. vi. 18.
