This verse emphasizes the criticality of the HolySpirit of Christ Jesus. -> He provides light -> He promotes fellowship -> He applies His blood to us -> He cleanses us of sin -> He removes guilt and condemnation <p>Jesus was manifested to serve the purpose of His HolySpirit which is to enable us to be reconciled to Him.<p>Our fellowship with the HolySpirit is totally dependent on our recognizing and honoring Him as the SpiritOfChrist Jesus.<p>Once we hear, believe and receive the Truth about the HolySpirit as manifested in His body called Jesus, we enter into the EternalLife of fellowship with Him.<p>How do we ^walk in the light^?   We allow the SpiritAndTruth that we have received to change -> how we talk, -> what we talk about, -> how we live and -> what we do with the life He has given us.
