Why is it important for Christ to be formed in us?

The phrase 'Christ formed in you' represents the spiritual reality of salvation and sanctification in a believer's life. According to Galatians 4:19, Paul expresses his anguish and desire for the Galatians to experience this transformation, which aligns with sovereign grace teaching that emphasizes the necessity of Christ's presence in the believer. The process includes the indwelling of the Holy Spirit, who cultivates one’s heart to reflect Christ's character and presence. This transformation is crucial because it results in a life led by faith, aligning our thoughts, actions, and desires with God's will, enabling us to live out the reality of being a new creation in Christ.
