A dog that returns to its vomit is like a fool who reverts to his folly (Proverbs 26:11)
Some people just like to keep returning to their sinful habits, no matter much you rescue them. They still think that the effect of their wrong choices will carry lesser or no negative effects. However such thinking is just plain wrong and is never supported by the Bible.
26 For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. 28 A man who has violated the law of Moses dies without mercy at the testimony of two or three witnesses. 29 How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace? 30 For we know him who said, “Vengeance is mine, I will repay.” And again, “The Lord will judge his people.” 31 It is a fearful thing to fall into the hands of the living God. (Hebrews 10: 26-30)
If the Lord God has rescued you from any evil, be very thankful to him. This is one life that you have, don’t let it go waste on the same things Jesus saved you from. Don’t keep presuming that God will keep saving you each time. The Bible clearly warns us not to put the Lord your God to the test. So simply don’t stand in a place of danger trusting in miracles, when God does not approve of you going there. What place am I talking about? Its the place of backsliding (into any sin) which is just one stop before the place of Eternal damnation!
Never go back to bad friends and bad relations
Do not be deceived: “Bad company ruins good morals.” Come to your right mind, and sin no more. For some have no knowledge of God. I say this to your shame. (1 Corinthians 15:33-34)
He that walketh with wise men shall be wise: but a companion of fools shall be destroyed. (Proverbs 13:20)
When Jesus saves you from bad friends, don’t walk right back with them, because they will 100% try to entice you to sin. Don’t displease the Lord God who has kept you from those who can ruin your soul with vile and sinful thoughts.
When you know that your past relationship, only made you an alcoholic or and immoral person, that relationship is simply going to lead you nowhere but in more evil things. Not worth your time nor effort, seriously!
Never go back to bad habits or sins
The backslider in heart will have his fill of his own ways, but a good man will be satisfied with his. (Proverbs 14:14)
“Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak.” ( Matthew 26:41)
But Jesus said to him, “No one, after putting his hand to the plow and looking back, is fit for the kingdom of God.” (Luke 9:62)
Devote yourselves to prayer, being watchful and thankful. (Colossians 4:2)
What pity will people have for the drug addict who keeps doing back to drugs even after being revived several times due to his or her multiple overdoses? Such a drug addict or let me say recovering drug addicts must take help from those not on drugs to remain off such a lifestyle that can harm the body and mind as well.
In a similar way, going back to alcoholism to ‘forget’ your problems won’t make your problems disappear. These will remain and being drunk will only make it more difficult to fix anything.
Talking about both the above examples and all other sins in general including stealing, idolatry, etc you need to stay clear of them all. The same Lord God who rescued you from these sins and bad habits can give you the grace to never fall back into them. All you need to do is faithfully pray to God to give you the strength to remain true to your calling in Jesus Christ.
“Backsliding, generally first begins with neglect of private prayer.” (J. C. Ryle)
Christ be with you!
