Rejoice, because your names are written in heaven

Luke 10:20
Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven. (KJV)

If we rejoice in the spiritual power we yield, then we may have missed the point. Similarly if we keep count of material success, even if it is counting the number of people we led to Christ or the size of our church, we have also missed the point. Every single spirit is important to God, like the Shepherd finding the lost one lamb out of a hundred. Salvation itself is the work of God. So what is our purpose? To bring the Good News to the unsaved and to disciple the saved. One commentary mentioned that Jesus never forced others, He usually begins His instructions with "If ....", not imposing on others with "You must ...."
