Warm greetings @charity9 
You’ve got some great input from Amethyst, Marsha, and Jan already- I just want to agree with what was said about there being plenty of Christian Witches out there! It is not only possible, but actually pretty common for people to combine their Christian (as well as other religious) beliefs and traditions with Wicca/paganism/witchcraft 
I remember @MeganB had a great video about it a while back, so let me share that with you here:
Christian Witchcraft: An Interview
I also remember a really inspiring discussion (here: Christian Witch) with some additional notes and lots of support that you might find helpful.
I am not personally a Christian Witch so I’ll step back to let others share their voices, but I did want to offer these resources as well as my support. You are very welcome here, Charity! 
Lots of love and many blessings to you
