John Wesley believed and taught the doctrine of Entire Sanctification, the idea that it is possible for a believer to achieve perfection in this life, based on Bible verses like:
Those who have been born of God do not sin, because God's seed abides in them; they cannot sin, because they have been born of God. — 1 John 3:9
and Jesus' command:
Be perfect, therefore, as your heavenly Father is perfect. — Matthew 5:48
Can someone explain what Christian Perfection or Entire Sanctification means?
