You cannot have a biblical assurance of salvation without a proper understanding of it; Thomas Brooks; http://www.gracegems.org/Brooks/heaven_on_earth5.htm In part he says this; For the better and further opening of this truth, premise with me these two things: [1.] First, No man can have any sure evidence to himself of his happiness and blessedness, from the promises of Scripture. [Isa 42:6; Isa 49:8; Joel 2:28; Ezek 32:26-27; Jer 32:40; Heb 8:10-12; Isa 32:15] The promises do not describe to whom salvation and all eternal blessings belong. The promise of giving Christ, of giving the Spirit, of giving a new heart, and of pardoning and blotting out sin—are all general promises. Now God is free to make good these to whom he pleases; therefore he often steps over the rich and chooses the poor; he often steps over the learned, and chooses the ignorant; he often steps over the strong, and chooses the weak; he often steps over the noble, and chooses the vile; he often steps over the sweet nature, and chooses the wicked nature, etc., that no flesh may glory, and that all may shout out "Grace, grace!" 1 Cor 1:25-29. [2.] Secondly, Though no man can have any sure evidence of his happiness and blessedness from the promises, because the promises do not describe the persons to whom salvation and all eternal blessings belong; yet these promises are of most choice and singular use. 1. The first gift. FAITH is a gift of God which brings the soul within the promise of everlasting blessedness, as the Scripture does everywhere evidence: " 2. The second gift. WAITING patiently on God is a gift which brings you within the promise of everlasting happiness and blessedness. 3. The third gift. HUNGERING and THIRSTING AFTER RIGHTEOUSNESS is a gift which brings the soul within the compass of the promise of everlasting happiness and blessedness: Matt 5:6, "Blessed are those who hunger and thirst after righteousness: for they shall be filled"; or as it runs in the Greek, "Blessed are those who are hungering and thirsting," intimating that wherever this is the present disposition of men's souls, they are blessed, and may expect spiritual repletions.
