The "Good person test" was formulated by Comfort. Using the law in evangelism goes back to the first century, and is spoken of extensively by the reformers, and even Charles Spurgeon (who said the same thing I did about the law).
Modern methods, which eschew the law, are not biblical, and will result in nothing but false converts. A person MUST recognize their sinfulness in order to be saved. They are either humble and contrite, having already realized their sinfulness, and are ready for the grace of the cross, or they are proud, arrogant, and have NOT realized their sinfulness, and MUST be shown the law of God.
To say that God will bless methods that are not in concert with His Word is foolishness...
the Gospel message is what the Lord blesses though...
preach/teach that we are sinners, Jesus died in our place, paid the sin debt owed to Gaod, and was traised from the dead...
THAT message is still the same, regardless if one using Evangelism explosion, way of the master, etc!
For its the work of the Holy Spirit to bring a sinner to conviction/awareness of their condition, NOT the method used!
