Will God forgive me for my wrongs?

As being a young and stupid person, I did a lot that I am ashamed for. I have broken commandments- once a friend took something from a store and I took something too (I was about 15 or 16). I was so in love (so I thought) that I thought by doing spells I could make him stay in love with me. I know I was very stupid and dumb. But now I am working to become a better person and keep having flashbacks of these episodes. This verse in the Bible scares me- Do not be deceived! Fornicators, idolaters, adulterers, male prostitutes, sodomites, thieves, the greedy, drunkards, revilers, robbers--none of these will inherit the kingdom of God" (1 Corinthians 6:9-10). I know I have done wrong and I have not stolen again or did witch craft since that time. Will God forgive me??
