"Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage." Galatians 5:1
Once Jesus has set you free from sin and the bondage of sin, it doesn't mean that that bondage won't try to come and reclaim your life. The enemy of you soul is out to destroy you. Your own flesh wants to destroy you. They will work together to try to get you to submit and return back to them. But you don't have to give in.
When you were set free from besetting sins, it was not just an act of seer will that delivered you. It was not your education that delivered you. It was not your ability that delivered you. It was not you; you did not deliver yourself. Jesus delivered you and He delivered you completely.
You do not have to give into the temptation to return to bondage. You do not have to fall back prey to the sins that once had you bound-- anger, hated, jealousy, fornication and other immoralities, addiction, or any other thing. When Jesus delivered you, He (as has already been said) delivered you completely and enabled you to stay delivered.
If you are being tempted to return to what you were once delivered from, look to Jesus who delivered you to begin with. Look to Him for strength. (His strength is made perfect in your weakness.) Look to Jesus the Author and Finisher of your faith. Stand firm in the victory that you have been given in Him. Remember, the Greater One is in you than is in the world. You don't have to give in or go back. You don't have to let it back in. You are more than a conqueror through Christ over what you were delivered from and over it being able to return.
Have a great day. Stand firm in the freedom that Christ Jesus has given you. You can because His freedom is complete and His ability to stand free is complete as well.
