How do we know that Jesus can truly set us free?

Jesus declares in John 8:36, 'If the Son therefore shall make you free, ye shall be free indeed.' This promise is rooted in the redemptive work of Christ, who fulfilled both the active and passive requirements of the law. By His perfect obedience and sacrificial death, He not only met the demands of the law for those He came to save but also provided a way for them to be reconciled to God without condemnation. This freedom is evident in the believer's life, demonstrated through a genuine faith in Christ, which is the evidence of His saving grace.
