There are enemies, adversaries and adverse powers unseen presented in great detail in scripture
Where things get interesting is understanding these operations in our own sorry hides, necessitating taking every thought captive
Lying hypocrisy merely shows captivity
Ignorance seems to be bliss
You said a couple of things worth discussing
You say we are captive and not collaborators, that is true as scripture says anyone that sins is a slave to sin. Romans 6 gets interesting some translations say when you were slaves to sin you were free from obligation to do good. That sounds like we would not be punished, but it rather reflected our inability to be obligated to righteousness because of our slavery to sin.
Jesus sets us free from this bondage if we wish it, or rather use our free will to choose Him. When we give ourselves freely to Christ, we become slaves of righteousness. Our old man passes away and all things become new.
We cannot do good works to earn God’s favor; He does not need our help. We need His. When we offer ourselves to God, He hears us and takes away our slavery to sin and makes us slaves of righteousness and we do good works. If we lack strength, we just need ask God who gives liberally to all who ask.
The devil or the adversaries are crafty, so they mix truth with lies in order to deceive. They say hey you can’t be saved by works(truth ), so don’t do them. If works cannot save you then it does not matter if you sin or do right, just believe and you will be fine. (Lie)
This deception fools souls into thinking that they are “saved” while they remain slaves to sin. Scripture says God has prepared for us good works that we should walk in them
We lack ability to do good of our own, but God grants us free will to choose whom we will serve.
When we are born again we are set free from our obligation to sin and our conscience becomes slave to righteousness. It does not matter the magnitude of our work, the smallest thing done gives glory to God, for He says if we are faithful in little, we will been given greater things to do, remember the woman with two pennies.
As we walk in good works, we learn from them, and learn of God. The basics are prayer, fasting and almsgiving. We do not do these things to boast, but to undergo training in righteousness
You will find, that the more you learn in good works, the more service you do, and the more joy you get from service. We do not seek honor, for what good is honor is those around us perish and their death causes grief in Our Lord?
God gives us joy in service, or we can listen to Satan who says works can’t save you don’t do them, and persecute everyone that tries to encourage you to do them
Be not deceived. Jesus calls us to work, but His yoke is easy and His burden light
