Why do Typical Christians say Jesus is their Master and Lord, but they choose to obey His enemy the devil and continue to live in sin?

Sanctification it is called (becoming holy) is actually a lifelong process. Some Christians are blessed to become holy at a young age, some deal with sins for many years (maybe because God is teaching them some lessons to overcome the sins, etc). So its not good to judge all sinners the same.

Are you asking a question, or making an accusation couched in a question? Since you don't elaborate, one can't help but conclude you are a troll.

A person can battle the devil and his demons using the rosary and fasting.

There is no such thing as a 'typical Christian.'

The Bible identifies either 'born again' regenerated souls or members of an evil impostor 'Christian' tradition called the 'way of Balaam,' (2 Peter 2:10-21, Jude 1:10-16).

Followers of 'Balaam' are greedy, sexually perverse, prone to slander authority, and even attempt to slander both GOD and Christ publicly by creating scandal in the Church. They especially focus on women and attempt to subvert existing authorities by appealing to their sense of injustice and to secret sexual desires. We have been dealing with them since the Church was founded. They tend to swell in numbers during eras when the effects of 'visitation' have grown far distant. 'Visitation' is the arrival of spiritual inspiration and genius leading to widespread repentance and social advancement across tribal and cultural lines. The last great era of 'visitation' led 'common' people to traverse the entire world with a message of universal brotherhood and tribal forgiveness offered as part of a 'New Covenant' in Christ. This culminated in the formation of the first 'university' system, dedicated to world peace through economic equality, to unmatched artistic and social genius, then the grand institutions and models which have given us the 'modern' world itself.

GOD explains to us that such 'visitation' events are planned and will create a series of previously unimaginable 'new worlds' each time, ultimately consummating in the return of Christ and the complete reformation of earth itself. In between however, we must endure dark eras where '...evil men and impostors will proceed from bad to worse, deceiving and being deceived." (2 Timothy 3:13).

The devil isn't real. Unless you want him to be.

Because they believe Jesus freed them from having to follow His strict Old Testament Laws and Commandments that Jesus said He didn't come to change one tittle.

WRONG ASSUMPTIONS...COMMUNION IS FOR FORGIVENESS...I DID THAT A MONTH AGO...STOP LYING...LOOK INTO YOUR OWN HEART...IS ASKER A CLONE??

Christians say "we represent Jesus" and then act like pricks...it's their way of calling Jesus a prick

...and a child rapist, and a murderer, and a liar, and all of the other things Christians do.

That's sort of the whole point. Being a Christian is about hating Jesus, but not having the balls to say it out loud.

Because Jesus sucks nuts.
