God isn't a dummy. Here is something to consider.
What would a person who truely believed in Jesus Christ live like? If I believe in Christ, I will obey His teachings and then I wouldn't do those things listed.
God has said what will happen to those who claim to have faith in Christ but don't live like they believe:
Mark 7:6-9
6 He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with [their] lips, but their heart is far from me.
7 Howbeit in vain do they worship me, teaching [for] doctrines the commandments of men.
8 For laying aside the commandment of God, ye hold the tradition of men, [as] the washing of pots and cups: and many other such like things ye do.
9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
Matt 7:16-21
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither [can] a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
