John Murray on assurance

Here is John Murray denying the truth of Hebrews 11:1 which says, "And faith is of things hoped for a confidence, of matters not seen a conviction":

"When we speak of the grounds of assurance, we are thinking of the ways in which a believer comes to entertain this assurance, not of the grounds on which his salvation rests. The grounds of salvation are as secure for the person who does not have full assurance as for the person who has" (John Murray, Collected Writings, Vol. 2, p. 270).

The foundation of the Christian's assurance is the SAME FOUNDATION of his salvation! Jesus Christ ALONE! The ground of the believer's assurance IS the ground of their salvation, and the ground of the believer's salvation IS the ground of their assurance. 

"Therefore, brothers, having confidence for the entering of the [Holy of] Holies by the blood of Jesus" (Hebrews 10:19).
Contrary to the self-righteous statements of John Murray, the person who does not have full assurance to enter the Holy of Holies by the blood of Jesus must necessarily seek to establish his own righteousness as a means of "[coming] to entertain this assurance" (cf. Romans 10:1-4). If this person would despair of and cease from establishing his own righteousness, and hope in the atoning blood and imputed righteousness of Jesus Christ alone, he would never doubt, he would never be shaken, for his salvation would be truly secure on the Rock of Jesus Christ.

“Truly my soul waiteth upon God: from him [cometh] my salvation. He only [is] my rock and my salvation; [he is] my defence; I shall not be greatly moved. … My soul, wait thou only upon God; for my expectation [is] from him. He only [is] my rock and my salvation: [he is] my defence; I shall not be moved. In God [is] my salvation and my glory: the rock of my strength, [and] my refuge,[is] in God” (Psalm 62:1-2,5-7). “They that trust in the LORD [shall be] as mount Zion, [which] cannot be removed, [but] abideth for ever. As the mountains [are] round about Jerusalem, so the LORD [is] round about his people from henceforth even for ever” (Psalm 125:1-2).
