Backsliding

And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel, which had appeared unto him twice, And had commanded him concerning this thing, that he should not go after other gods: but he kept not that which the LORD commanded. (1 Kings 11:9-10)

I will hear what God the LORD will speak: for he will speak peace unto his people, and to his saints: but let them not turn again to folly. (Psalms 85:8)

Come, and let us return unto the LORD: for he hath torn, and he will heal us; he hath smitten, and he will bind us up. (Hosea 6:1)

I will heal their backsliding, I will love them freely: for mine anger is turned away from him. (Hosea 14:4)

But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea. (Matthew 18:6)

And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God. (Luke 9:62)

Wherefore let him that thinketh he standeth take heed lest he fall. (1 Corinthians 10:12)

O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you? This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith? Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh? (Galatians 3:1-3)

Brethren, if any of you do err from the truth, and one convert him; Let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins. (James 5:19-20)
