Calvinism and Arminianism both teach that full repentance (turning away from) of sin is required for salvation. When we repent it must be in the heart. It must be full. That does not mean that we will never sin again, because we are still in this rotten flesh and eagerly await the coming of Christ and the Kingdom, in which we will be sinless, but we do not keep committing the same exact sin over and over again joyfully without caring. In repentance, we actively seek to fight our sin. We use Scripture, as we seek to walk according to the Spirit, because Scripture is the only true weapon against our flesh.
That said, I quote from Octavius Winslow:
" Be careful of not making a Saviour of faith. There is a danger—and it cannot be too vigilantly guarded against—of substituting the work of the Spirit for the work of Christ; this mistake it is that leads so many of God's saints to look within, instead of without, themselves for the evidences of their calling and acceptance; and thus, too, so many are kept all their spiritual course walking in a state of bondage and fear, the great question never fully and fairly settled, or, in other words, never quite sure of their sonship. The work of Christ is a great and finished work; it is so glorious that it can admit of no comparison, so complete that it can allow of no addition, and so essential that it can give place to no substitution. Precious as is the work of the Holy Ghost in the heart, and essential as it is to the salvation of the soul, yet he who places it where the work of Jesus ought only to be, deranges the order of the covenant, closes up the legitimate source of evidence, and will assuredly bring distress and uncertainty into his soul. " Righteousness, peace, and joy," are the fruit of a full belief in the Lord Jesus Christ; and he who looks for them away from the cross, will meet with disappointment: but they are found in Jesus. He who looks away from himself, from his vileness, guiltiness, emptiness, and poverty, fully and believingly unto Jesus, shall know what the forgiveness of sin is, and shall experience the love of God shed abroad in his heart.
If, then, your faith is feeble and tried, be not cast down; faith does not save you. Though it be an instrument of salvation, and as such, is of vast importance, it is but the instrument; the finished work of Immanuel is the ground of your salvation, yea, it is your salvation itself. Then make not a saviour of your faith; despise it not if it is feeble, exult not in it if it is strong, trample not on it if it is small, deify it not if it is great; such are the extremes to which every believer is exposed. If your faith is feeble and sharply tried, it is no evidence that you are not a believer; but the evidence of your acceptance in the Beloved, is to arise from Jesus alone; then I let your constant motto be, " looking unto Jesus "; looking I to him just as you are; looking unto him when faith is feeble; looking unto him when faith is tried; looking unto him when faith is declining, yea, looking unto him when you fear you have e no faith. Look up, tried and tempted soul! Jesus is the Author, the Sustainer, and he will become the Finisher of thy faith. All thou wantest is in him. One glimpse, dim though it be, of his cross,—one touch, trembling though it be, of his garment,—will lift thee from thy lowest depths, lighten thy heaviest burthen, gild thy darkest prospect, and when thou arrivest at Jordan's brink, will bear thee safely through its swellings, and land thee on the sunny and verdant shores of Canaan. Let this be your prayer, urged unceasingly at the throne of grace until it is answered—" Lord, increase my faith "; and then, with holy Paul, you too shall be enabled with humble assurance to exclaim, " I know in whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day!'" (Octavius Winslow. Personal Declension and Revival of Religion in the Soul. Page 88, 89: Banner of Truth, 1993.)
May God give to those who are His full comfort in the cross of Christ, that we were crucified with Him and resurrected to new life with Him. There is no comfort but in the cross of Christ for all those who repent and trust Jesus completely.
Ben
peace in Christ
