How do we know that we are part of Christ's people?

The assurance of being part of Christ's people is tied directly to the doctrine of sovereign election. Ephesians 1:4-5 states that God chose us in Christ before the foundation of the world to be holy and blameless. This election is not based on our actions or merits but solely on God's grace and love. Moreover, the transformative work of the Holy Spirit in renewing our hearts enables us to willingly embrace Christ as our King. As indicated in John 6, all that the Father gives to the Son will come to Him, illustrating the certainty of being a member of His elect people. Therefore, one can know they are part of Christ's people through faith and the evidence of a changed life, continuing in the grace that secures their place in Him.
