How do we know we are branches of Christ?

According to John 15:2, every branch in Christ that does not bear fruit is taken away, while those that do bear fruit are pruned to produce more. This indicates that true branches—in other words, genuine believers—will display the fruits of faith, repentance, and perseverance. True faith is a gift from God, leading to genuine repentance and ongoing perseverance in trusting Christ. If an individual has been regenerated and converted by the Holy Spirit, they will recognize Christ as their only hope of salvation, thereby affirming their identity as one of His branches.
