We can know we are part of the true church by recognizing the evidence of spiritual life and belief in Christ.
To determine if we are members of the true church, we should examine whether we have been spiritually quickened by the Holy Spirit, as stated in Ephesians 2:1. The Apostle mentions that those who were once dead in trespasses and sins are made alive in Christ. If we exhibit spiritual life, a desire to obey God's commands, and a genuine faith in our Lord, then we can have confidence in our membership within the true church. Importantly, this assurance is not solely based on self-reflection but on the transformative work of God's grace in our lives, evidenced by a growing understanding of and adherence to His Word.
