Luke 15:11-32.
This is the one of most famous Jesus' parable about the prodigal son. This young man came back to his father with repentance for what he did. His father was so glad that the lost son got back and held a big celebration. His brother was jealous because he did always good following his father. Father said to him. "You are always with me. Everything that's mine is yours. We must celebrate because your brother was lost and has been found."
We can clearly see that the God wants us to come back with repentance, God will welcome us just like this father did.
