You can only cast out demons in the name of Jesus Christ the Lord God!!! God so loved the world that He gave his one and only Son...Jesus Christ that whosoever believes on him shall never perish shall never die!!! John 3:16 there is a hell and a Heaven and you are welcome to receive Jesus and depart drom the first option
..our sin has separate us from God...our orrogancy...our pride...our anger...our envy. .our lying...our greed...our curse words...our lust...etc etc...God is Holy and He cannot dwell in the presence of sinful man...God loves us and came in the body of Jesus to redeem us from the great judgment which is approaching the earth. Jesus loves you!!! Believe in the Lord Jesus Christ and you shall be saved!!!
