Religion makes it complicated; a ritual makes it cheap. It is neither. The good news is a Person, crucified and risen for you, received by faith.
Repentance is the change of mind that turns to Christ — it is part of believing, not a separate work added to faith. It is not cleaning yourself up first: a changed life is the fruit that follows faith, never the price of entry.
