People who repent understand their sinful state and empty life. Salvation requires repentance and escaping sin.
“Or do you despise the riches of his kindness and forbearance and patience? Do you not realize that God’s kindness is meant to lead you to repentance?” (Romans 2:4)
The Holy Spirit is the agent of the new spiritual birth.
“Jesus answered: In all truth tell you, no one can see the kingdom of God without being born from above. Nicodemus said, ‘How can anyone who is already old be born? Is it possible to go back into the womb again and be born?’ Jesus replied: In all truth I tell you, no one can enter the kingdom of God without being born through water and the Spirit; what is born of human nature is human; what is born of the Spirit is spirit. Do not be surprised when I say: You must be born from above. The wind blows where it pleases; you can hear its sound, but you cannot tell where it comes from or where it is going. So, it is with everyone who is born of the Spirit.” (John 3:3-8)
“I am quite confident that the One who began a good work in you will go on completing it until the Day of Jesus Christ comes.” (Philippians 1:6)
I use to work with teens who didn’t like to go to mass. They were taken to Catholic Renewal Ministries Conference’s. At one the main speaker was Fr. DeGrandis. He prayed over them and gave each a booklet on teen forgiveness. When they got home TV’s were put on and they saw St. Padre Pio having mass. At our next meeting they said that they didn’t want to go to mass on Sunday’s ONLY. Now it was as soon as possible and they wanted to do only more for the church. Rosary’s were tatted for them and we asked a priest to speak to them. Praise the Lord!
I told them about metanoia.
