True freedom in Christ is to live in the freedom that He alone can give to us.
In John 8:31-36 Jesus is speaking to those Jews who believed on Him. He proclaims a true freedom to them, the freedom from the slavery to sin. This inner freedom is can only be experience through the obedience of faith. This kind of faith is set before us in the life of Abraham. Romans 4 tells us that when Abraham believed God, even without the law, it was counted to Him as righteousness.
So our faith in Christ, when He speaks a living Word into our hearts through the Holy Spirit, will be counted to us as righteousness.
However, James 2:14-24 tells us that if faith does not work in our life, it is dead being by itself. So Abraham's faith was perfected through his obedience a 2nd he was called the friend of God. James 2:23
This faith is also perfected through the covenant of circumcision. Not the circumcision of the physical flesh, but as Romans 2:28-29 tells us it now is a circumcision of the heart. Step
