2 Bible Verses about The Reality Of Sin

If we claim to have no sinful practices [in our lives], we are self-deceived and are not being truthful about the matter. [But] if we confess our sins [to God], He is faithful [to His promise] and righteous [in His judgment], and will forgive us of those sins and cleanse us from all of our wrongdoing. If we claim that we have not committed sins, we are [in effect] calling God a liar [i.e., because He says we have] and His word [i.e., the real truth about the matter] is not in our hearts.

Therefore, just as sin came into the world through [the action of] one man [i.e., Adam] and [physical] death through that sin, so [physical] death has spread to all people, because all people have sinned. [Note: This difficult passage (verses 12-21) seems to be saying that the entire human race must experience physical death because of Adam's sin (I Cor. 5:22), which is somehow considered to be everyone's sin. See Murray, pp. 180-187, for a thorough discussion].
