In my opinion, your just living life how Jesus did. Jesus used herbs and plants to heal the sick and wounded, prayed over these people similar to how witches do today. Read the Old Testament, the original Bible, and you will learn that Jesus was much like witches today. Communing with Nature and God wasn't something uncommon for Ancient Christians, but Modern Christianity makes it seem evil. In my opinion, man-made things are evil, and things that are made in the Eye of God are holy (animals, plants and humans). God made these plants for a reason. I am not a Christian Witch, this is just my opinion on the subject. I don't think you will burn in hell unless you try to harm someone using magick. Follow your heart, Jesus wouldn't let you go down a path that would ultimately result in you going to hell, would he? No, he wouldn't. I hope this helps you along your path.
A seasoned Green Witch am I, With plant wisdom and magic to share.
A child of the flowers am I, With blossoms budding from my hair.
A friend of the Fairies am I, A crown of leaves and flowers I wear.
A daughter of the Earth am I, Walking Her ways with feet ever bare.
A sister of the waters am I, Flowing wild and free without a care.
At one with the blowing winds am I, Singing softly through the midnight air.
A keeper of the fire am I, Let me kindle your passions if you dare.
Connected in Spirit with You am I, Fused together as one in prayer.
