Can you understand this?

At all events, let us beware of resting satisfied with the confession of our lukewarmness to our fellow-creatures, without "pouring out our heart before the Lord." There is a fulness of grace in our glorious Head to "strengthen the things that remain, that are ready to die," as well as at the beginning to "quicken" us when "dead in trespasses and sins." Abundant, also, are the promises and encouragements to poor, dry, barren souls,—"I will heal their backslidings; I will be as the dew unto Israel: he shall grow as the lily, and cast forth his roots as Lebanon." (Hos. xiv. 4-6.) For what purpose are promises such as these given, but that they may be "arguments," wherewith to "fill our mouth," when in the contrition of faith we again venture to "order our cause before God?" And "will he plead against us with his great power?" No; but "he will put his strength in us" (Job, xxiii. 4-6); and we shall yet again "run the way of his commandments" (Verse 32) with an enlarged heart.
