How do we know if we are loving each other in truth?

According to John, to love one another means loving in truth, which is rooted in the love that Christ has for His church. This kind of love conflicts with the world's definition of love, which often revolves around feelings and emotions. True biblical love involves laying down one's life for others, as Christ did for us. Thus, love is evidenced through acts of selflessness and a commitment to the truth that we confess. If we are unable to love our fellow believers in this manner, we may not fully grasp the love that God has for us, which is a crucial aspect of our fellowship in the body of Christ.
