How does one receive completeness in Christ?

According to 1 Corinthians 1:30, it is by God's grace and initiative that believers are made complete in Christ Jesus. This process begins when an individual recognizes their need for salvation and accepts Christ as Lord and Savior. It is not by human effort but by divine work that one becomes united with Christ. When a person sincerely comes to Christ in faith, they are placed in Him, thereby receiving the fullness of His righteousness, wisdom, and sanctification. This transformation is essential for a true understanding of one's identity and completeness before God.
