What is the work of God according to Jesus?

In John 6:29, Jesus clarifies to His followers that the 'work of God' is singular: to believe in Him whom the Father has sent. This declaration simplifies the complex theological landscape into one core requirement—faith. Rather than a list of moral imperatives or religious rituals, belief in Christ encapsulates the essence of what God desires from humanity. This aligns with Reformed theology, which posits that salvation is solely through faith and not by human works, revealing the depth of divine grace at work in bringing sinners to Himself through Christ.
