And we know that all things work together for good to those who love God, to those who are the called according to His purpose. – Romans 8:28

I believe this to be the crowning work of God in man, that His people should be perfectly delivered from evil…Every work of the Spirit of God upon the new nature aims at the purification, the consecration, the perfecting of those whom God in love has taken to be His own. Yea, more; all the events of Providence around us work towards that one end: for this our joys and our sorrows, for this our pains of body and griefs of heart, for this our losses and our crosses-all these are sacred medicines by which we are cured of the disease of nature, and prepared for the enjoyment of perfect spiritual health. All that befalls us on our road to heaven is meant to fit us for our journey’s end. Our way through the wilderness is meant to try us, and to prove us, that our evils may be discovered, repented of, and overcome, and that thus we may be without fault before the throne at the last. We are being educated for the skies, meetened for the assembly of the perfect. It doth not yet appear what we shall be; but we are struggling up towards it; and we know that when Jesus shall appear, we shall be like Him, for we shall see Him as He is. We are rising: by hard wrestling, and long watching, and patient waiting, we are rising into holiness. These tribulations thresh our wheat and get the chaff away, these afflictions consume our dross and tin to make the gold more pure. All things work together for good to them that love God; and the net result of them all will be the presenting of the chosen unto God, not having spot or wrinkle, or any such thing. ~ C.H. Spurgeon
