The scripture assumes that conversion must be from the world to the Kingdom of God. From the kingdom of darkness to the Kingdom of light. From the kingdom of Satan to the Kingdom of God's dear Son. Conversion includes a death, burial and a resurrection into a whole new life. Kingdom salvation should lift us up and seat us with Christ in heavenly places.
Conversion involves a whole different perspective of our relationship with earth.
From the heavenly viewpoint it should be clear that our citizenship is in heaven and we are strangers and visitors here on earth. The scripture speaks about forsaking all to follow Jesus. It speaks about suffering for the gospel and laying down our life for Christ. That he who saves his life will lose it. Unless you take up your cross daily and follow Me, you can't be My disciple.
