The Bible tells us so. Did someone tell you that morality and truth are relative? You need to learn to discern and distinguish the lies of the adversary from the true sayings of your Maker. I shall pray that you see the light of the noon-day sun before you are eternally lost. Don't goof around. You can fool little children into thinking they are just monkeys swinging from vines, but I pity you poor hell bound soul if you should decide to take this path.
Romans
1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
1:19 Because that which may be known of God is manifest in them; for God hath shewed [it] unto them.
1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that
they are without excuse:
1:21 Because that, when they knew God, they glorified [him] not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
1:22
Professing themselves to be wise, they became fools,
Luke
17:1 Then said he unto the disciples, It is impossible but that offences will come: but woe [unto him], through whom they come!
17:2 It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.
