Holiness is on another level of justification...a higher righteousness. God doesn't judge the world by the standard of holiness....but on what they have done with what they have been given. Loving others as ourselves. On that level ALL the earth will be judged.
Holiness is about walking as Jesus walked without sin. VERY FEW will walk like that. Jesus said that the narrow way was very difficult.
When God accepts us we are born of the Spirit. We have an experience of holiness and eternal life as a sample of what it's like to walk like that. If we want to have that life...we will have to pay the cost of entering into it. Like buying oil for the lamp. Of course we can last awhile with the original gift of grace. But there is also a throne of grace where we go to BUY the full measure of grace that lasts us until we fail grace.
No, that is growth into Christ-likeness in character...in righteousness. No one can grow INTO holiness. Holiness is to be where God is...in His presence....that we may partake of HIS holiness. We are never holy of ourselves.
Yes. But most believers are in a transitional walk between being under the law and under grace. Like the wilderness walk we read about in the book of Exodus. From there we can be led by the Spirit and enjoy times of refreshing from the Lord. If we want to walk in holiness we need to offer ourselves to God in full surrender. He decides if we are accepted into the Beloved or not.
Stole this from google:
Sanctification results from the supernatural presence and power of the Holy Spirit working in a Christian's life (Galatians 5:22–26; Ephesians 3:20; 2 Corinthians 12:9–10). It requires a change of heart, an alignment of the will with God's will.
It is the work of a lifetime. It is not automatic. Sorry. We are in different stages of Christian growth. Someone likened it to a corn plant. A growing seedling is a perfect seedling where it is development wise, and at each stage of its growth, it is perfect for what it is at the time, but not done growing.
