How do we know God's holiness affects our relationship with Him?

God's holiness is a fundamental aspect of His nature, representing His separation from sin and utter perfection. Isaiah 59:2 states, 'your iniquities have separated between you and your God.' This means that because of sin, humanity cannot have a direct relationship with a holy God. Instead, there is a significant barrier that can only be overcome through God's grace and action. Without understanding this holiness, we risk underestimating the seriousness of our sin and the necessity of divine intervention for reconciliation.
