Saying, “Sorry,” is a good thing, but not everyone knows this—to say it or to hear it. Jesus taught in no uncertain terms: Forgive others, lest ye not be forgiven.
Repent, knowing that God wants to forgive. Come back to the light. Return from whence you fell. Repentance is a good thing; it is the basis is hope.
When someone makes a mistake, say so; it’s not an accusation. Accusing, pointing the finger of shame, calling a vote to throw someone overboard—all on account of error—is not any kind of teaching one would learn from the Bible or even tolerate. The purpose of calling out someone on a problem is to restore the person, granting the invitation to return to the simple, safe road that leads to Life.
The Bible’s view of repentance is that repentance leads to hope. An apology is not an admission of fault as legal testimony against oneself; it is a response to the summons issued by God Himself that we return to Him, even when we return to Him for the first time.
The first time a person walks the path of repentance that leads to hope, simply understanding at the heart-level that Jesus died at the Cross to cover the cost of our guilt, that person becomes a “Christian”. That’s all a Christian is—someone who repented to Jesus, accepting his hope in return. Becoming Christian is not about “church”, real estate, weekly schedules, or money given to the pastor. Becoming Christian is nothing more than the pure acknowledgment that Jesus is one’s personal, forgiving, hope-giving “Christ”—the Messiah who saves the whole world—thus, accordingly, believing the “Christ” already came to give hope to those who repent to him. “Christianity” is nothing more or less.
A non-Christian plainly does not believe that the “Christ” has already come, but still waits for some future hope other than Jesus.
Non-Christians are incapable of understanding the idea of repenting toward hope. Self-proclaimed “Christians” who shame others or can’t simply say, “Sorry,” without feeling overwhelming shame themselves might not be Christians since every Christian, by definition, has experienced Jesus’s gift of hope in exchange for us repenting to him.
