What the Bible says about Ignoring God's Advice
(From Forerunner Commentary)
God's claim on mankind is illustrated by His dealing with Adam and Eve and their response. Biblical Christianity, the true way of life of the Father and Son, has a claim on humanity's attention and loyalty because humans are Their creation and the clear aim of Their concerns from beginning to end in Scripture. In fact, Their message is aimed directly at mankind, indicating that the Father and Son do not hide from humanity.
However, most people ignore Scripture's truths in terms of practical application in daily life. Even the Redeemer's Sermon on the Mount, though admired by many as wonderful advice, is not obeyed but ignored. How do we know this is true? Within His sermon, Jesus states that God has not done away with His law (Matthew 5:17-19), but people ignore His words, doing what satisfies the demands of their desires. Instead, humans follow the pattern established by their original parents. At the beginning, Adam and Eve took of the Forbidden Tree despite God's warning, and most human beings have followed their examples.
