How do we know we are new creatures in Christ?

The assurance that we are new creations in Christ is affirmed by observable changes in our lives. 2 Corinthians 5:17 tells us that if anyone is in Christ, they are a new creation; the old has passed away, and all things have become new. This transformation is manifested in a believer’s attitude towards sin and righteousness. The presence of a longing to pursue God's will, a hatred for the sin that once dominated, and the active engagement in good works are signs of this new nature.

Additionally, the Holy Spirit’s work within us confirms this identity. Romans 8:9 highlights that if anyone does not have the Spirit of Christ, they do not belong to Him. Therefore, the internal desire for holiness and transformation, as well as visible fruits of good works, serve as a witness to the reality of our regeneration, reinforcing our standing in Christ and our ultimate hope in Him.
