One of the main purposes of the doctrines of grace - Arthur W. Pink

“The doctrines of grace are intended for a further purpose than that of making up a creed. One main design of them is to move the affections; and more especially to reawaken that affection to which the heart oppressed with fears, or weighed down with cares, is wholly insufficient—even the love of God. That this love may flow perennially from our hearts, there must be a constant recurring to that which inspired it and which is calculated to increase it; just as to rekindle your admiration of a beautiful scene or picture, you would return again to gaze upon it. It is on this principle that so much stress is laid in Scripture on keeping the truths which we believe in memory: "By which also you are saved, if you keep in memory what I preached unto you" (1 Cor. 15:2). "I stir up your pure minds by way of remembrance," said the apostle (2 Pet. 3:1). "Do this in remembrance of me" said the Saviour. It is, then, by going back in memory to that hour when, despite our wretchedness and utter unworthiness, God called us, that our affection will be kept fresh. It is by recalling the wondrous grace that then reached out to a hell-deserving sinner and snatched you as a brand from the burning, that your heart will be drawn out in adoring gratitude. And it is by discovering this was due alone to the sovereign and eternal "purpose" of God that you were called when so many others are passed by, that your love for Him will be deepened.”

Arthur W. Pink, Comfort for Christians

in Christ — Octavius Winslow

“There is therefore now no condemnation for those who are in Christ Jesus.” — Romans 8:1

"The believer is in Christ as Noah was enclosed within the ark, with the heavens darkening above him, and the waters heaving beneath him, yet not a drop of the flood penetrating his vessel, not a blast of the storm disturbing the serenity of his spirit. The believer is in Christ as Jacob was in the garment of the elder brother when Isaac kissed and blessed him. He is in Christ as the poor homicide was within the city of refuge when pursued by the avenger of blood, but who could not overtake and slay him."

— Octavius Winslow

“Christ is given us to use” — C.H. Spurgeon

“I will give You for a covenant of the people.” — Isaiah 49:8

“Christ is in the covenant to be used. God never gives his children a promise which he does not intend them to use…Christ is given us to use. Believer, use him! I tell thee again, as I told thee before, that thou dost not use thy Christ as thou ought to do. Why, man, when thou art in trouble, why dost thou not go and tell him? Has he not a sympathizing heart, and can he not comfort and relieve thee? No, thou art gadding about to all thy friends save thy best friend, and telling thy tale everywhere except into the bosom of thy Lord. Oh, use him, use him. Art thou black with yesterday’s sins? Here is a fountain filled with blood; use it, saint, use it. Has thy guilt returned again? Well his power has been proved again and again; come use him! use him! Dost thou feel naked? Come hither, soul, put on the robe. Stand not staring at it; put it on. Strip, sir, strip thine own righteousness off, and thine own fears too. Put this on, and wear it, for it was meant to wear. Dost thou feel thyself sick? What, wilt thou not go and pull the night-bell of prayer, and wake up thy physician? I beseech thee go and stir him up betimes, and he will give the cordial that will revive thee…

Oh, believer, do use Christ, I beseech thee. There is nothing Christ dislikes more than for his people to make a show-thing of him and not to use him. He loves to be worked. He is a great laborer; he always was for his Father, and now he loves to be a great laborer for his brethren. The more burdens you put on his shoulders the better he will love you. Cast your burden on him. You will never know the sympathy of Christ’s heart and the love of his soul so well as when you have heaved a very mountain of trouble from yourself to his shoulders, and have found that he does not stagger under the weight. Are your troubles like huge mountains of snow upon your spirit? Bid them rumble like an avalanche upon the shoulders of the Almighty Christ. He can bear them all away, and carry them into the depths of the sea. Do use your Master, for for this very purpose he was put into the covenant, that you might use him whenever you need him.”

— C.H. Spurgeon, Christ in the Covenant

unity & division among all people of the world — R. Kent Hughes

“All people are united to one another both by their ancestry and by their responsibility to their Creator God. But at the same time all the world’s people are divided by geography and language and ethnicity and culture – and most of all by their fallenness and sin, which separates them both from God and each other. So, what is the answer for a people so united and yet profoundly divided? The answer is embedded deep in Genesis where Adam and Eve suffered division from God and each other through their sin, and God responded to Satan with an oracle that promised that one of her offspring would undo his work by crushing his head:

“I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head and you shall bruise his heel.” (Genesis 3:15)

That was a divine prophesy of the cross, describing how Satan will strike the heel of Christ (the suffering of the cross) and how Christ will crush Satan’s head (through Christ’s death and glorious resurrection). The only hope for Adam and Eve, who were so sundered from God and each other (and from the whole world, which would be likewise divided), is through the offspring of Adam and Eve – and ultimately Jesus Christ.”
