Thomas Goodwin on the Seal of the Spirit

"The seal of the Spirit is the proper work that answereth to baptism. Therefore it is called "baptism in the Spirit" (Acts 1:5, 11-16) because it is that fruit of baptism that answereth the outward seal".

Thomas Goodwin on the Baptism of the Holy Spirit

"There is a light that cometh and overpowereth a man's soul and assureth him that God is his and he is God's and that God loved him from everlasting ... It is a light beyond the light of ordinary faith ... the next thing to heaven; you can have no more, you can have no more until you come hither ... It is faith elevated and raised up beyond its ordinary rate, it is the electing love of God brought home to the soul".
