When it comes to deliverance under the New Covenant, you need to know two things:

Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son - Colossians 1:13

Submit yourselves therefore to God. Resist the devil, and he will flee from you. - James 4:7

You don’t need to go through a complicated system to find the spiritual roots of the sickness, trauma, sin, or anything else that’s ungodly in your life. Instead, you need to stand in your identity in Christ and your authority in Christ. Then, as you stand and renew your mind, your heart becomes persuaded, and you become impervious to lies and deception. And the devil can’t touch you, just like Jesus.

I will no longer talk much with you, for the ruler of this world is coming, and he has nothing in Me. - John 14:30

Beware works that look spiritual but are actually efforts of the flesh mindset. If you’re trying to get something from God by doing something in the spiritual realm, you are probably “in the flesh.” Meaning, you think you can get something from God based on a work like giving, repenting, forgiving, rebuking, and so on.

I made a social media post recently that said, “you can’t add to or improve upon Christ’s finished work, you can only enjoy it.” 98% of the comments were grateful for this powerful truth. But there will always be those people who bring up the need for “works” when talking about the finished work of Jesus.

When the topic of the complete sufficiency of the sacrifice or freedom from the Law comes up, these passages usually enter the conversation.

As the body without the spirit is dead, so faith without deeds is dead. James 2:26

For we are God’s workmanship created in Christ Jesus to do good works which God prepared in advance for us to do. Ephesians 2:10

But this passage should also be part of the conversation.

For he who has entered His rest has himself also ceased from his works as God did from His. Hebrews 4:10

Because of this passage.
