First off, being around someone who isn’t Christian doesn’t make you not Christian. Second off that vid is a bunch of gossip.
About the ‘little gods’ thingy, when you become a Christian the Holy Spirit lives in you, and he is fully capable of performing miracles through you. You ain’t no ‘god’, but God definitely works through you. It’s nothing you can boast about, God can make a donkey talk for Pete’s sake, but yes, Christians have power over the Devil.
“But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.””
Acts 1:8 ESV
““Truly, truly, I say to you, whoever believes in me will also do the works that I do; and greater works than these will he do, because I am going to the Father.”
John 14:12 ESV
(That’s Jesus talking)
The Holy Spirit and Spiritual gifts are real folks.
