Our sins were forgiven after believing in the Lord, but we still often sin; how can we finally escape the bondage of sin?

The Answer from God’s Word:

The sins of man were forgiven through the agency of the incarnate God, but this does not mean that man no longer has sin within him. The sins of man could be forgiven through the sin offering, but as for just how man can be made to sin no more, and how his sinful nature may be extirpated completely and transformed, he has no way of solving this problem. The sins of man were forgiven, and this is because of the work of God’s crucifixion, but man continued to live within the corrupt satanic disposition of old.

This being so, man must be completely saved from his corrupt satanic disposition, so that his sinful nature may be completely extirpated, never to develop again, thus enabling the disposition of man to be transformed. This would require man to grasp the path of growth in life, to grasp the way of life, and to grasp the way to change his disposition. Furthermore, it would require man to act in accordance with this path, so that his disposition may gradually be changed and he may live under the shining of the light, so that all that he does may be in accord with the will of God, so that he may cast away his corrupt satanic disposition, and so that he may break free from Satan’s influence of darkness, thereby emerging fully from sin. Only then will man receive complete salvation. … Therefore, after that stage of work was finished, there still remained the work of judgment and chastisement. This stage is to make man pure by means of the word and thereby give him a path to follow. … This stage is more meaningful than the previous one, as well as more fruitful, for now it is the word that directly supplies man’s life and enables the disposition of man to be completely renewed; it is a much more thorough stage of work. Therefore, the incarnation in the last days has completed the significance of God’s incarnation and completely finished God’s plan of management for man’s salvation.
… By means of this work of judgment and chastisement, man will fully come to know the filthy and corrupt substance within his own self, and he will be able to change completely and become clean. Only in this way can man become worthy to return before the throne of God. All the work done this day is so that man can be made clean and be changed; through judgment and chastisement by the word, as well as through refinement, man can purge away his corruption and be made pure. Rather than deeming this stage of work to be that of salvation, it would be more apt to say it is the work of purification. In truth, this stage is that of conquest as well as the second stage in the work of salvation. It is through judgment and chastisement by the word that man arrives at being gained by God; and it is through the use of the word to refine, judge, and disclose that all of the impurities, notions, motives, and individual aspirations within man’s heart are completely revealed. For all that man may have been redeemed and forgiven of his sins, it can only be considered as God not remembering the transgressions of man and not treating man in accordance with his transgressions. However, when man, who lives in a body of flesh, has not been set free from sin, he can only continue to sin, endlessly revealing his corrupt satanic disposition. This is the life that man leads, an endless cycle of sinning and being forgiven. The majority of men sin in the day only to confess in the evening. This way, even if the sin offering is forever effective for man, it will not be able to save man from sin. Only half the work of salvation has been completed, for man still has a corrupt disposition.

from “The Mystery of the Incarnation (4)” in The Word Appears in the Flesh

In his life, if man wishes to be cleansed and achieve changes in his disposition, if he wishes to live out a life of meaning, and fulfill his duty as a creature, then he must accept God’s chastisement and judgment, and must not allow God’s discipline and God’s smiting to depart from him, so he can free himself from the manipulation and influence of Satan and live in the light of God. Know that God’s chastisement and judgment is the light, and the light of man’s salvation, and that there is no better blessing, grace or protection for man. Man lives under the influence of Satan, and exists in the flesh; if he is not cleansed and does not receive God’s protection, then man will become ever more depraved. If he wishes to love God, then he must be cleansed and saved. …

… If man is not cleansed, then he is of the filth; if he is not protected and cared for by God, then he is still a captive of Satan; if he is not judged and chastised, then he will have no means of escaping the oppression of the dark influence of Satan. The corrupt disposition that you show forth and the disobedient behavior that you live out are sufficient to prove that you are still living under the domain of Satan. If your mind and thoughts have not been cleansed, and your disposition has not been judged and chastised, then your entire being is still controlled by the domain of Satan, your mind is controlled by Satan, your thoughts are manipulated by Satan, and your entire being is controlled by the hands of Satan. …

… Today’s truth is given to those who yearn for and seek it. This salvation is granted to those who yearn to be saved by God, and is not only meant to be gained by you, but is also so that you can be gained by God. You gain God in order that God can gain you. Today I have spoken these words to you, and you have heard them, and you should practice according to these words. In the end, when you put these words into practice will be when I have gained you through these words; at the same time, you will have also gained these words, which is to say, you will have gained this supreme salvation. Once you are made clean, you will have become a real human being.
