Jesus sends His Holy Spirit to everyone, to tell them about Him, someway, somehow. And more than once, you will have been witnessed to.
If you are convicted in your heart, and choose to return to God and look to Jesus, to trust in Him as your Saviour, He has promised to save you to the uttermost. You can have a personal and intimate relationship with God Almighty. Free gift, offered to all.
Jesus is God. Nobody else can save you from your sin.
