The Bible is not about you. The Bible is also not about me. The Bible is about Jesus Christ (John 5:39-45; Luke 24). It is about who He is and what He has done.
Sadly, heretics like Erwin McManus narcigete biblical passages to make the Bible about them. McManus did that in his train-wreck of a book called Chasing Daylight. There is one Jesus. There is one John the Baptist, and we are not it (contrary to what McManus thinks).
John the Baptist preached repentance and the forgiveness of sins. Notice he did not just take all comers for baptism.
3 In those days John the Baptist came preaching in the wilderness of Judea, 2 and saying, “Repent, for the kingdom of heaven is at hand!” 3 For this is he who was spoken of by the prophet Isaiah, saying:
“The voice of one crying in the wilderness:
‘Prepare the way of the Lord;
Make His paths straight.’ ”
4 Now John himself was clothed in camel’s hair, with a leather belt around his waist; and his food was locusts and wild honey. 5 Then Jerusalem, all Judea, and all the region around the Jordan went out to him 6 and were baptized by him in the Jordan, confessing their sins.
7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “Brood of vipers! Who warned you to flee from the wrath to come? 8 Therefore bear fruits worthy of repentance, 9 and do not think to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones. 10 And even now the ax is laid to the root of the trees. Therefore every tree which does not bear good fruit is cut down and thrown into the fire. 11 I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire. 12 His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather His wheat into the barn; but He will burn up the chaff with unquenchable fire.”
