Titus 1:16. Many people profess to know God, but they are without conscience. Many people may really believe they know God, but in their works they deny Him. Many people may talk about their love of God and profess His word, but their action show they are without conscience (Titus 1:15-16, "Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled. They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.").

2 Kings 17:15. If the purpose of a relationship is based on self-centeredness, this is a sign of a bad relationship. An example of this is where the pretty girl hangs out with the ugly girl. In a lot of cases, the pretty girl is in the relationship to be adored and to even look prettier. The ugly girl is there because of envy in the hopes that some of the prettiness might rub off on her. This is a relationship based on pride and envy. These types of relationships will eventually deteriorate into hate and loathing. Many of our human relationships are based on self-centeredness.

2 Thessalonians 2:10. Another aspect when we define delusions is that someone that is deluded shows no love of truth. People may say they love God, but what are their actions.

Our truth becomes, “if it feels good, do it.” We say, “everyone else believes it or does it, so it must be the true way.” A lover of truth seeks truth. If God sees that you do not love the truth, he will let you go your own way.

1 Samuel 15:23. Even when God does good things for us, our sin nature will rebel. This happened with Saul, Israel's first king. As time pasted while Saul was king, he became full of himself thinking he knew better than God and God's prophet, Samuel. He overtly disobeyed God's word that Samuel had given him. God ultimately rejected Saul as king because of his defiant behavior and anointed David to take his place (1st Samuel 15:23, "For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry.
