How does God's holiness relate to our need for Christ?

God's holiness is foundational to understanding our need for Christ. The sermon highlights that God must judge sin, and His standard is not human morality but His holiness. In Isaiah 28:17-18, God warns that those not resting on the righteousness of Christ will face judgment, as their false refuges will not stand. The statement that 'the soul that sins shall die' signifies that without Christ's atonement, we cannot escape the consequences of sin. Only through faith in Him can we be declared righteous and escape the impending judgment.
