The nature of sanctification: purity and separation
Sanctification comprises of two foundational elements. The first is inner purity. (Psalm 66:18). The second element of sanctification is separation from a worldly entourage and sinful practices. This implies separation from false believers in the church. (1 John 2:15).
(2 Timothy 3:5). Separating oneself is not just for the sake of separation, but for serving Christ efficiently. (2 Tim 2:21).
The purpose of sanctification
A legalistic approach to sanctification sets personal performance as a goal. But sanctification according to the Word of God leads the believer to becoming more like Christ. This in fact is the plan of our Heavenly Father, that we be Christ-like. (Ephesians 4:22-24).
