Through Jesus, we have victory!!

These verses pretty much say it all: Beware of religious tradition of men that isn't according to the Bible. The fullness of God is in Christ. We find salvation by repentance, baptism in Jesus name, and infilling of the Holy Ghost. And we find victory over the devil through Jesus!

"Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwelleth all the fulness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power: in whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened [made alive] together with him, having forgiven you all trespasses; blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; and having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it." - Colossians 2:8-15 KJV (Acts 2:38)
