How do we know we are true Christians?

The assurance of one's status as a true Christian is evidenced through the fruits of the Spirit. According to John 15, a disciple who abides in Christ will exhibit characteristics such as repentance toward God and holiness in life. Without these evidences, claims of spiritual life are hollow, indicating that the individual lacks a real union with Christ. As the New Testament states, where there is no fruit, there is no life; therefore, the presence of these spiritual fruits is crucial for assurance of salvation.
