Backsliding is a problem faced in all religion.
Backsliding makes things worse on our soul and is a problem, which all of God‘s religions face; and must overcome: CHRISTIANITY: 2 Peter: 2:20 “For if after they have escaped the pollutions of the world through the knowledge of The Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.” 2 Timothy: 3:2 “For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, 3:3 Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, 3:4 Traitors, heady, highminded, lovers of pleasures more than lovers of God;” JUDAISM: Jeremiah: 11:10 “They are turned back to the iniquities of their forefathers, which refused to hear My words; and they went after other gods to serve them: the house of Israel and the house of Judah have broken My covenant which I made with their fathers.” Jeremiah: 11:11 “Therefore thus saith The LORD, Behold, I will bring evil upon them, which they shall not be able to escape;”
ISLAM: 12. Allah (God) did aforetime take a Covenant from the Children of Israel, and We appointed twelve captains among them, and Allah said: “I am with you: if ye (but) establish regular prayers, practice regular charity, believe in My apostles, honor and assist them and loan to Allah a beautiful loan, verily I will wipe out from you your evils, and admit you to gardens with rivers flowing beneath; but if any of you, after this, resisteth faith, he hath truly wandered from the path of rectitude.”
(The Qur’an (Yusuf Ali tr), Surah 5)
25. “But those who break the Covenant of Allah (God), after having plighted (pledged) their word thereto and cut asunder those things which Allah has commanded to be joined, and work mischief in the land — on them is the Curse; for them is the terrible Home!”
(The Qur’an (Yusuf Ali tr), Surah 13)
16. “If ye show obedience, Allah will grant you a goodly reward, but if ye turn back as ye did before, He will punish you with a grievous Penalty.”
(The Qur’an (Yusuf Ali tr), Surah 48)
ZOROASTRIANISM: 86. “The cow driven astray invokes Him for help, longing for the Stables:” “When will that bull, Mithra, the lord of wide pastures, bring us back, and make us reach the stables? When wilt He turn us back to the right way from the den of the Druj where we were driven?” “That man does not follow the way of the Law, O Zarathushtra!” “Let him praise the Law, O Spitama Zarathushtra! and long for it and embrace the whole of the Law, as an excellent horse turns back from the wrong way and goes along the right one,”
(Zoroaster, The Zend-Avesta, Khorda Avesta – Book of Common Prayer pt. 1 and Avesta Fragments)
Denkard. Zoroaster, “(A man originally religious) performs in this world deeds known in the world as those of Farehbut and Aibibut. And, owing to this, the man becomes as obscured (darkened) and damaged as he (before) was glorious in the world through (good) deeds. Such rule being itself (calculated) for evil (destruction), owing to it, that good man, — his glory (fame) being lessened, — is reduced to the lowest rank. There is no resurrection (rising again) for the people in this world.”
HINDUISM: “If Yudhishthir, fond of gambling, played a heedless reckless game, Lost his empire and his freedom, was it then Duryodhan’s blame, And if freed from shame and bondage in his folly played again, Lost again and went to exile, wherefore doth he now complain? Weak are they in friends and forces,”
(Hindu, Mababharata (R. Dutt, abridged tr))
BUDDHISM: 24. “Whoever having got rid of the forest of desires, gives oneself over to that forest-life, and who, when free from the forest runs back into the forest, look at that person, though free, running back into bondage.”
(Buddhist, Dhammapada – Sayings of the Buddha 2 (tr. J. Richards))
BABI RELIGION: “Strive that by your deeds you may bear witness to the truth of these words of God, and beware lest, by ‘turning back,’ He may ‘change you for another people,’ who ‘shall not be your like,’ and who shall take from you the Kingdom of God.”
(Shoghi Effendi, The Dawn-Breakers, p. 93)
BAHA’I FAITH: 308.12 “It is not easy for people to learn the Bahá’í way, to overcome their inherited prejudices or to resist their personal temptations. This way takes time, is subject to checks and backsliding, but one can see, looking at the past……. years, that there is an overall advance that is astonishing in the light of the obstacles to be overcome, and is accelerating with every passing decade.”
(Bahá’í Faith, The Universal House of Justice, Messages 1963 to 1986, p. 516)
