Why is it important to sanctify ourselves before God?

Sanctification refers to the act of being made holy or set apart for God. In Exodus 19:10-11, God instructs Moses to sanctify the people, preparing them for His presence. This preparation is crucial because it symbolizes our need to be cleansed from sin and made acceptable to a holy God. Similarly, in the New Testament, believers are called to be sanctified in Christ, who through His blood cleans us and presents us spotless before the Father (Ephesians 5:25-27). Without sanctification, we cannot approach God, as His holiness demands that we honor His presence and submit to His requirements, ultimately pointing to our need for Christ's redemptive work.
