Could it be said that putting our wants and desires above the wishes of others is the root of all sin? Since sin is a biblical subject, we will observe a few passages from the Bible to reach a God approved answer to this question.
First, we must define sin. Sin is the transgression of God’s law (I John 3:4). We sin when we fail to fulfill any or all of God’s laws. One can sin in thought (Matthew 5:22, 28; I John 3:15), by actions (Romans 2:32) and by our words (Col 3:8-9). All sin falls into these three categories of our lives. The apostle John stated, “For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world (I John 2:16).” All sin is a product of the world and cannot be associated with our Heavenly Father.
Several New Testament passages list the sins in which one might engage. These verses outline the types of behavior that are unacceptable to God (Rom 1:29-32, I Cor 5:11, Galatians 5:19-21; 2 Tim 3:2-4, Rev 21:8)
