I've recently wanted to buy a guitar but I didn't know if it was greed or not, so I asked some people on the true Christian subreddit for their advice, they said it was ok. But just in case I asked my mom the night before I bought my guitar if she wanted me to buy it, she said I should wait, so I agreed to wait. Today, since we were out of town, I went to a guitar store, and I played an amazing guitar. When I was back in my car I got an idea, that idea was to say to my mom, "oh, I played an amazing guitar and it was only so and so dollars." So, without thinking, I told that to my mom knowing she would let me buy the guitar, and she did. So now, I'm ashamed of guilt-tripping my mother, and I'm worried that God didn't want me to buy that guitar. What should I do? Was it God's will? Do I sell the guitar? Also, one other thing that I might add is that I struggle with legalism, I go crazy over whether I can or can not do something, so now I'm worried that this is just another useless question that I'm going crazy over. Please tell me your opinion and what the Bible says about this.
