How do we know salvation is all about Christ?

According to Ephesians 2:4-5, despite our deadness in sins, God, in His rich mercy, brings us to life together with Christ. This demonstrates that salvation’s essence does not lie within human decision or merits, but solely on the work of God through Jesus. The preacher highlights that many attempt to insert humanity into the gospel narrative, yet the reality is that it is God's will and work that save us. Christ is the focal point, as our understanding of salvation is tied to who He is and what He has accomplished.
