We always have a choice to ask God for the truth. Those who do not ask God or ask Him expecting Him to say what they want will not be able to think clearly to hear the truth when it waltzes right in front of them.
The only way to discover the truth is to be willing to ask God and eliminate from our thinking anything that we have heard or was taught that was not truth.
Most people choose to believe what they like or are familiar with rather than the Bible.
In fact most people are so dedicated to their own ideas they interpret the Bible in terms of those ideas instead of believing what God actually said.
Our culture has misinterpreted the Bible in many ways to maintain their comfort level. The truth isn't all that important to them, only that they believe what they want.
Sadly too many decisions to believe what they want are based on the pressure of others in the culture who do not follow the Bible.
Choose any cliche we hear often these days from Christians, and something will be wrong with it. Christians have taken their mantras from the secular community and attempted to make them fit the Bible. It is astounding how many people believe something is Biblical but it is not anywhere in the Bible.
I would be interested in some cliches you have heard that people think are Biblical but are not.
