1 John 1:6-8

Amplified Bible

⁶ 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; ⁷ 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]. ⁸ If we say we have no sin [refusing to admit that we are sinners], we delude ourselves and the truth is not in us. [His word does not live in our hearts.]
