John 1:12 – But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:

2 Peter 1:4 – Wereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.

Paul's eyes were ever fastened on the unseen and eternal. Realizing that he was fighting against supernatural powers, he placed this dependence on God, and in this lay his strength. It is by seeing Him who is invisible that strength and vigor of soul are gained and the power of earth over mind and character is broken." (Acts of the Apostles – 363)

When the soul surrenders itself to Christ, a new power takes possession of the new heart. A change is wrought which man can never accomplish for himself. It is a supernatural work, bringing a supernatural element into human nature. (Desire of Ages – 324)

"By this shall all men know that ye are My disciples," said Jesus, "if ye have love one to another." When men are bound together, not by force or self-interest, but by love, they show the working of an influence that is above every human influence. Where this oneness exists, it is evidence that the image of God is being restored in humanity, that a new principle of life has been implanted. It shows that there is power in the divine nature to withstand the supernatural agencies of evil, and that the grace of God subdues the selfishness inherent in the natural heart. (Desire of Ages – 678)

The reason so many fail to be successful laborers is that they act as though God depended on them, and they are to suggest to God what He chooses to do with them, in the place of their depending on God. They lay aside the supernatural power and fail to do the supernatural work. They are all the time depending on their own and their brethren's human powers. (Faith and Works – 27)

Without the grace of Christ, the sinner is in a hopeless condition; nothing can be done for him; but through divine grace, supernatural power is imparted to the man and works in mind and heart and character. (Faith and Works – 100)

Our condition through sin is unnatural, and the power that restores us must be supernatural, else it has no value. There is but one power that can break the hold of evil from the hearts of men, and that is the power of God on Jesus Christ. (Amazing Grace – 104) 

Christ promised that the Holy Spirit should abide with those who wrestle for victory over sin, to demonstrate the power of divine might by endowing the human agent with supernatural strength and instructing the ignorant in the mysteries of the kingdom of God. . . . (Amazing Grace – 212)

Through His merits and imparted power they will be "more than conquerors." Supernatural help will be given them, enabling them in their weakness to do the deeds of omnipotence. . . . (In Heavenly Places – 252)

I am bidden to call upon the churches to awake out of sleep. We must contend with invisible, supernatural foes. (Reflecting Christ – 201)

By thousands of voices, all over the earth, the warning will be given. Miracles will be wrought, the sick will be healed, and signs and wonders will follow the believers. (Colporteur Ministry – 151)

When the Saviour said, "Go, . . . teach all nations," He said also, "These signs shall follow them that believe; In My name shall they cast out devils; they shall speak with new tongues; they shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover." The promise is as far-reaching as the commission. Not that all the gifts are imparted to each believer. The Spirit divides "to every man severally as He will." 1 Cor. 12:11. But the gifts of the Spirit are promised to every believer according to his need for the Lord's work. The promise is just as strong and trustworthy now as in the days of the apostles. "These signs shall follow them that believe." This is the privilege of God's children, and faith should lay hold on all that it is possible to have as an endorsement of faith. (Desire of Ages – 823) 

You may say, "Why not, then, take hold of the work, and heal the sick as Christ did?" I answer, You are not ready. …There must be a reformation throughout our ranks; the people must reach a higher standard before we can expect the power of God to be manifested in a marked manner for the healing of the sick. . . . (Medical Ministry – 15) 

Christ's love in the heart, revealing through the life its wondrous power--this is the greatest miracle that can be performed before a fallen, quarreling world. Let us try to work this miracle, not in our own power, but in the name of the Lord Jesus Christ, whose we are and whom we serve. Let us put on Christ, and the miracle-working power of His grace will be so plainly revealed in the transformation of character that the world will be convinced that God has sent His Son into the world to make men as angels in character and life. (The Upward Look – 233)
