Ok, quit calling yourself a Christian then if you want to lie. Lying is forbidden by God in the ten commandments, as well as in multiple verses.
John 8:44
44 You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
Revelations 22:15
15 Outside are the dogs, those who practice magic arts, the sexually immoral, the murderers, the idolaters and everyone who loves and practices falsehood.
