How do we know that Jesus Christ makes us free?

Jesus asserts in John 8:36 that true freedom is granted by Him: 'If the Son therefore shall make you free, ye shall be free indeed.' This freedom is described as a transformation where believers move from bondage to life. In verse 34, He explains that anyone who sins is a slave to sin, and it is only through faith in Christ's redemptive work that one can experience true liberation. This is consistent with historical Reformed theology, which emphasizes that salvation and freedom from sin are purely by grace through faith in Jesus Christ alone.
