People talk a lot on this site about having a relationship with God. How do you know that you have a relationship with God? How do you know the difference between your own thoughts and thoughts that supposedly come from God? Some people claim God told them to do horrible crimes, like drown their children. They thought it was real. How do you know your thoughts are real?
We know, instinctively, just from life itself, some of what is right and wrong - like murder is wrong. There is more than just listening to what life tells us, as Christians also have God's word and the Holy Spirit that never goes against that living Word. They are all in agreement and would never break God's commandments or love, as love fulfills God's law.
What wonderful things does life say of our Creator and then what does the fact that sin and death entered in to that picture of life do to mar what was once perfect? In my opinion, life, in the light of God's word, is the greatest language and witness to God that there is, and even death witnesses to the fall of mankind depicted in the scriptures. We can see that life is complex in beauty and design, with fantastic potential, yet it is flawed with the hatred, selfishness of man, and the horror of death. These things are given account of in the Bible, truthfully, with the extremities of what sin and death have done not being glossed over for the sake of what could be a nice little book of axioms. No the Bible shows that it takes the life blood of God Himself to save mankind back from the sin and death that Adam fell into and left as an inheritance for all of mankind that followed through his seed.
We have life and the other witnesses of God to help us, and the Christian also receives the Spirit of God as a helper, but it would never be to go against God's laws. The spirit of the world is deceived by the devil, who has been and always will be a deciever. Those that do go against God's laws, yet claim it is God that instructs them, have been deceived by the "father of lies", the devil, or one of his messengers, as one third of the angels fell with the devil after they rebelled against God before this world was ever set into the light.
As I have read the Bible, I have seen that the words contained within it are played out in life, showing me the wisdom of God so that I can live right before Him. Jesus told us that His words were spirit and life to those who would hear them and do them. People that claim to murder in God's name are led by the spirit of this world which is owned by the devil until Jesus returns.
1Co 2:12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God.
2Corinthians 4:4 Satan, the god of this evil world, has blinded the minds of those who don’t believe, so they are unable to see the glorious light of the Good News that is shining upon them. They don’t understand the message we preach about the glory of Christ, who is the exact likeness of God.
