Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord,  according as His divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of Him that hath called us to glory and virtue… – 2 Peter 1:2, 3

My brethren, you who are partakers of the divine nature, know that by nature you were dead in trespasses and sins, and would have continued so until this day if there had not been an interposition of divine energy on your behalf. There you lay in the grave of your sin, rotten, corrupt. The voice of the minister called to you, but you did not hear. You were often bidden to come forth, but ye did not and could not come. But when the Lord said, “Lazarus, come forth,” then Lazarus came forth; and when He said to you, “Live,” then you lived also, and the spiritual life beat within you, with joy and peace through believing. This we ought never to forget, because, let us never fail to remember, that if our religion is a thing which sprang from ourselves, it is of the flesh, and must die. That which is born of the flesh in its best and most favourable moments, is flesh, and only that which is born of the Spirit is spirit. “Ye must be born again.” If a man’s religious life be only a refinement of his ordinary life, if it be only a high attainment of the natural existence, then is it not the spiritual life, and does not prepare him for the eternal life before the throne of God… Now the implantation of this new principle, called the spirit, is a work of divine power. Divine power! What stupendous issues are grasped in that term, divine power! It was this which digged the deep foundations of the earth and sea! Divine power, it is this which guides the marches of the stars of heaven! Divine power! it is this which holds up the pillars of the universe, and which one day shall shake them, and hurry all things back to their native nothingness. Yet the selfsame power which is required to create a world and to sustain it, is required to make man a Christian, and unless that power be put forth, the spiritual life is not in any one of us.~ C.H. Spurgeon

…to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ… – 2 Peter 1:1

Be pleased to notice the word “righteousness.” It is a faith in the righteousness of our God and our Saviour. In these days, certain divines have tried to get rid of all idea of atonement; they have taught that faith in Jesus Christ would save men, apart from any faith in Him as a sacrifice. Ah, brethren, it does not say, “faith in the teaching of God our Saviour;” I do not find here that it is written, “faith in the character of God our Saviour, as our exemplar.” No, but “faith in the righteousness of God our Saviour.” That righteousness, like a white robe, must be cast around us. I have not received Jesus Christ at all, but I am an adversary and an enemy to Him, unless I have received Him as Jehovah Tsidkenu, the Lord our righteousness. There is His perfect life; that life was a life for me; it contains all the virtues, in it there is no spot; it keeps the law of God, and makes it honourable; my faith takes that righteousness of Jesus Christ, and it is cast about me, and I am then so beauteously, nay, so perfectly arrayed, that even the eye of God can see neither spot nor blemish in me. Have we, then, today a faith in the righteousness of God our Saviour? For no faith but this can ever bring the soul into a condition of acceptance before the Most High. ‘Why,” saith one, “these are the very simplicities of the gospel.” Beloved, I know they are, and thanks be to God, it is the simplicities which lie at the foundation; and it is rather by simplicities than by mysteries that a Christian is to try himself and to see whether he be in the faith or no. Put the question, brethren, have we, then, this like precious faith in God and our Saviour Jesus Christ? ~ C.H. Spurgeon

“He hath raised us up together, and made us sit together in heavenly places in Christ Jesus.”- Ephesians 2:6

That is very wonderful. We have not only left the dead, and become joined to Christ, but we are made to sit in heaven with Christ. A man is where his head is, is he not? And every believer is where his Head is; and if we are members of Christ’s body, we are in heaven. It is a very blessed experience to be able to walk on earth, and look up to heaven; but it is a higher experience to live in heaven, and look down on the earth; and this is what the believer may do. He may sit in the heavenlies; Christ is there as his Representative. The believer may take possession of what his Representative is holding on his behalf. Oh, to live in heaven, to dwell there, to let the heart be caught up from this poor life into the life that is above! This is where we should be, where we may be if we are quickened by the divine life.

We are in this position, that God is now working in us, through this divine life, to make us the most wonderful reflectors of His grace that He has yet formed. He has raised us up together, and made us sit together in heavenly places in Christ Jesus, “that in the ages to come He might shew the exceeding riches of His grace in His kindness toward us through Christ Jesus.” The ages to come will have for their wonder the quickened children of God. When God made the world, it was a wonder, and the angels came from afar to see His handiwork. But when Christ makes the new creation, they will say no more that God made the heaven and the earth, but they will say in higher strains, “He made these new-born men and women. He made for them, and in them, new heavens and a new earth.” ~ C.H. Spurgeon
