Link Isa 48:8 & Rom 3:23: all have sinned.
Connect Isaiah 48:8 with Romans 3:23 on the universality of sin.

Setting the Scene in Isaiah

Isaiah 48:8: “You have never heard; you never understood; from of old your ear has not been opened. For I knew how treacherous you are; from birth you have been called a rebel.”

• God addresses Israel, exposing a deep-rooted, congenital rebellion.

• “From birth” highlights that sinfulness is not merely learned; it is inherent.

• The words “treacherous” and “rebel” underscore a heart posture that resists God’s rule.


Identifying the Universal Problem

Romans 3:23: “for all have sinned and fall short of the glory of God.”

• Paul broadens Isaiah’s diagnosis from Israel to “all.”

• “Fall short” pictures an unbridgeable gap between human effort and God’s perfect glory.

• Sin, therefore, is not restricted by ethnicity, era, or environment—it is universal.


Connecting Isaiah 48:8 to Romans 3:23

• Isaiah pinpoints the problem: rebellion “from birth.”

• Romans confirms the scope: “all have sinned.”

• Together, the passages teach that the sin nature Isaiah observed in Israel lives in every human heart, making Romans 3:23 a logical New-Testament echo of Isaiah 48:8.


Tracing the Theme Through the Bible

Genesis 6:5 – “every inclination of the thoughts of his heart was altogether evil all the time.”

Psalm 51:5 – “Surely I was brought forth in iniquity; I was sinful when my mother conceived me.”

Ecclesiastes 7:20 – “Surely there is no righteous man on earth who does good and never sins.”

Isaiah 53:6 – “We all like sheep have gone astray; each one has turned to his own way.”

1 John 1:8 – “If we say we have no sin, we deceive ourselves, and the truth is not in us.”


Implications for Every Believer

• Sin is a birth condition, not just a behavior pattern.

• Religious heritage or moral effort cannot erase innate rebellion.

• Honest confession aligns us with God’s assessment rather than human standards.


The Only Remedy Revealed

Romans 3:24 – “and are justified freely by His grace through the redemption that is in Christ Jesus.”

Isaiah 53:5 – “He was pierced for our transgressions… by His stripes we are healed.”

• Faith in Christ addresses both guilt (acts of sin) and nature (being a rebel from birth), offering the righteousness we lack and restoring us to God’s glory.

How can Isaiah 48:8 encourage repentance and reliance on God's grace today?
