³ What we have seen and [ourselves] heard, we are also telling you, so that you too may ^[a]realize and enjoy fellowship as partners and partakers with us. And [this] fellowship that we have [which is a ^[b]distinguishing mark of Christians] is with the Father and with His Son Jesus Christ (the Messiah).

¹³ But when He, the Spirit of Truth (the Truth-giving Spirit) comes, He will guide you into all the Truth (the whole, full Truth). For He will not speak His own message [on His own authority]; but He will tell whatever He hears [from the Father; He will give the message that has been given to Him], and He will announce and declare to you the things that are to come [that will happen in the future].

⁹ God is faithful (reliable, trustworthy, and therefore ever true to His promise, and He can be depended on); by Him you were called into companionship and participation with His Son, Jesus Christ our Lord.
