While the darkness was coming on one, the darkness left the other. The sorcerer was not seeing anything, but the deputy saw it all. Both were in spiritual darkness, but the sorcerer gained physical darkness as well, while the deputy was delivered and found spiritual Light. Bro. Jeff explains more as he wraps up the account of this spiritual battle.
Acts 13:12 KJV
12 Then the deputy, when he saw what was done, believed, being astonished at the doctrine of the Lord.
Acts 13:7
7 Which was with the deputy of the country, Sergius Paulus, a prudent man; who called for Barnabas and Saul, and desired to hear the word of God.
John 3:1-21
1 There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: 2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him. 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. 4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother’s womb, and be born? 5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and [of] the Spirit, he cannot enter into the kingdom of God. 6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. 7 Marvel not that I said unto thee, Ye must be born again. 8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit. 9 Nicodemus answered and said unto him, How can these things be? 10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? 11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. 12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you [of] heavenly things? 13 And no man hath ascended up to heaven, but he that came down from heaven, [even] the Son of man which is in heaven. 14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: 15 That whosoever believeth in him should not perish, but have eternal life. 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
Acts 8:30-39
30 And Philip ran thither to [him], and heard him read the prophet Esaias, and said, Understandest thou what thou readest? 31 And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him. 32 The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth: 33 In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth. 34 And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man? 35 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus. 36 And as they went on [their] way, they came unto a certain water: and the eunuch said, See, [here is] water; what doth hinder me to be baptized? 37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. 38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. 39 And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing.
Hebrews 2:3-4
3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard [him]; 4 God also bearing [them] witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
Matthew 11:1-5
1 And it came to pass, when Jesus had made an end of commanding his twelve disciples, he departed thence to teach and to preach in their cities. 2 Now when John had heard in the prison the works of Christ, he sent two of his disciples, 3 And said unto him, Art thou he that should come, or do we look for another? 4 Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: 5 The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.
John 20:30-31
30 And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: 31 But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
Romans 10:17
17 So then faith [cometh] by hearing, and hearing by the word of God.

Colossians 1:13
13 Who hath delivered us from the power of darkness, and hath translated [us] into the kingdom of his dear Son:
1 Thessalonians 1:9-10
9 For they themselves shew of us what manner of entering in we had unto you, and how ye turned to God from idols to serve the living and true God; 10 And to wait for his Son from heaven, whom he raised from the dead, [even] Jesus, which delivered us from the wrath to come.
