Why is it important for Christians to focus on 'Jesus only'?

'Jesus only' encapsulates the core of Christian faith, reinforcing that salvation and the entirety of the believer's life relies solely on Christ’s accomplished work. The Transfiguration exemplifies this when the voice of God the Father commands the disciples to hear Him alone (Matthew 17:5). This signifies that Jesus is not one of many great figures, but the unique Son of God who provides eternal life and mediates our relationship with the Father. By focusing on 'Jesus only,' believers are liberated from confusion and distractions posed by other spiritual influences. It is a call to trust in His sufficiency for all needs, affirming that salvation is entirely upon His grace without any merit of our own. Thus, it aligns with the sovereign grace doctrine that places Christ at the center of faith and worship.
