1 John 1:4-7

We are writing these things to you so that our joy [in seeing you included] may be made complete [by having you share in the joy of salvation]. This is the message [of God’s promised revelation] which we have heard from Him and now announce to you, that God is Light [He is holy, His message is truthful, He is perfect in righteousness], and in Him there is no darkness at all [no sin, no wickedness, no imperfection]. If we say that we have fellowship with Him and yet walk in the darkness [of sin], we lie and do not practice the truth; but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].
