How do we know that salvation involves human responsibility?

Salvation encompasses both divine grace and human responsibility, as highlighted in Philippians 2:12 where believers are instructed to work out their salvation. This implies that, post-conversion, Christians have a responsibility to ensure their faith is evident in their daily conduct. The active participation in living out faith does not conflict with sovereign grace; rather, it complements the work God is doing within us. In fact, Philippians 2:13 underscores that it is God who works in us to will and to do His good pleasure, illustrating that while we are responsible for our actions, it is God who enables and empowers them.
