We are sanctified by God through His election, the sacrifice of Christ, and the work of the Holy Spirit in our new birth.
Sanctification is a work of God wherein He sets His people apart for His use. In Jude 1:1, believers are described as 'sanctified by God the Father,' referring to God's choosing of them for salvation. The Son also sanctifies His people through His sacrifice, as seen in Hebrews 10:10, where it states that through Christ's offering, we are made holy. Additionally, the Holy Spirit plays a crucial role in this process, as mentioned in Romans 15:16, where God makes us sanctified by regenerating us and giving us a new nature. This dual nature in believers—a sinful nature and a new, holy nature—creates the ongoing struggle with sin, but it also assures us that we have been made holy by God's sovereign grace.
