Can and Will a True Christian Stop Sinning in This Life? ...and, if so, How?
In other words, this question is already conditionally predicated on the Existence of the One True God of Heaven -- and that Jesus Christ was the Son of God before His Incarnation, that He laid down His Divine Power (but not His Divine Authority) to become a Man, and that He took up His Divine Power again when He Ascended to Heaven 40 days after His Crucifixion and Resurrection.
Thus, when everyone considers their answers, please keep in mind these verses of Scripture -- and keep in mind that I'd like to hear answers in your own words, rather than more Scripture (unless I've missed a very telling one):
