This study goes over why it is necessary to stop sinning, which is what "repent" actually means, what the circumcision of the heart is, what the baptism of the holy spirit causes, and the purpose of the first coming of Jesus Christ to not only atone for sin, but to end it. The study can be found in English here Repentance and Sin No More, Perfection and Born of the Spirit | Wisdom of God or in Spanish here Arrepentimiento y No Pecar Más, Perfección y Nacido del Espíritu | Sabiduria de Dios , let us begin a discussion on this matter here.
