Oh, dear child. I was raised in the Pentecostal Church as well. Heartland Conference of the IPHC. I live less than 5 miles from IPHC headquarters in Oklahoma.
Weather magick is a gift! Christ did it (Mark 4:35-41)! This is a gift from God that is part of your birthright in salvation through Christ. Anyone who says what you do is evil simply need to check the Bible again.
Any time you have questions about how Wicca and Christianity fit together, let me know. I am your resident Messianic Jewish Pentecostal Baptist Witch. :)
