'Changing' in the Bible

“Then I will give to the peoples [clear and pure speech from] purified lips [which reflect their purified hearts],That all of them may call on the name of the Lord,To serve Him shoulder to shoulder (united).

“Repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life], for the kingdom of heaven is at hand.”

“As for me, I baptize you with water because of [your] repentance [that is, because you are willing to change your inner self—your old way of thinking, regret your sin and live a changed life], but He (the Messiah) who is coming after me is mightier [more powerful, more noble] than I, whose sandals I am not worthy to remove [even as His slave]; He will baptize you [who truly repent] with the Holy Spirit and [you who remain unrepentant] with fire (judgment).

So that we are no longer children [spiritually immature], tossed back and forth [like ships on a stormy sea] and carried about by every wind of [shifting] doctrine, by the cunning and trickery of [unscrupulous] men, by the deceitful scheming of people ready to do anything [for personal profit].

Those whom I [dearly and tenderly] love, I rebuke and discipline [showing them their faults and instructing them]; so be enthusiastic and repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will].
