Why is Christ crucified essential for Christian obedience?

Christian obedience is deeply affected by the reality of Christ crucified. Without understanding His sacrifice, obedience can become mere legalism or dead works. When believers recognize that Christ was crucified for their sins, their obedience is transformed into a response of love and gratitude for what He has done. In Galatians 2:20, Paul affirms that it is through faith in Christ that one lives, emphasizing the grace-based motivation behind true Christian living. Thus, the gospel empowers believers to obey out of thankfulness rather than obligation.
