From that time Jesus began to preach, saying, “Repent, for the kingdom of heaven is at hand.”
— Matthew 4:17
When he stepped into his public ministry, he encouraged people to repent and believe the Gospel. We instantly think of sin when we hear the word “repent,” meaning we think repenting is always about confessing our sin. Repenting from sin is important, but that’s not what Jesus was talking about.
Definition of Repent
Repent is the Greek word metanoeō, which is a combination of two words; meta and noeō. Meta means; with, after, behind. It’s a preposition that modifies the verb noeō. Noeō means; to perceive with the mind, to understand, to have understanding, to think upon, heed, ponder, consider.
Metanoeō or Repent means; to change one's mind, to turn one’s mind for the better, heartily to amend with abhorrence of one's past sins.
So repentance does have to do with turning away from sin but more specifically it is about changing our minds about the beliefs that drive sin. Repentance is when you do a deeper work than just apologizing for a sinful action. It’s when you go into your heart beliefs and make adjustments.
What you believe generates your thoughts. Your thoughts then lead to feelings and emotions. Those feelings and emotions then give way to action. So whether it be anger or adultery, sin is the fruit of your beliefs and what you think on. To repent is to turn away from the thinking that leads to sin. In this passage, Jesus teaches us to change the way we think about God’s kingdom because he’s bringing us good news.
