How do we know that we are taught by Christ?

According to the sermon, there are three indicators that we have been taught by Christ: we have heard Him, we have been taught by Him, and what we have learned aligns with the truth in Jesus. Hearing Christ means recognizing His voice through His Word, while being taught by Him involves receiving doctrines and practices that lead to a God-honoring life. The truth in Jesus encompasses both the knowledge of salvation and the call to holiness. This threefold evidence affirms our relationship with Christ and the authenticity of our faith.
