Where did you learn that?
From the Word of God. But without turning to the Word of God people will continue to be confused and conflict with one another about what is true and what is not.
Man’s views are often divisive because they put their own spin on everything according to their motives. But if we believe in God and trust His explanations because He is God and therefore All-Knowing, then we will have agreement.
By turning to God, we see with His Eyes and find truth because God is All Truth and perfect.
So a person claims that the Quran teaches violence but God says that the military expeditions of Muhammad were purely defensive. Now I wasn’t there nor the person interpreting the Quran taught violence but God WAS there and is All Knowing so I rely on God as the Eye Witness rather than someone who wasn’t there and is just speculating with their finite, fallible and human error prone mind.
God reveals to us the truth through His Prophets. Only by turning to Them can we get the truth. Believing ourselves to be right is the biggest mistake we can make because we are fallible and error prone. If we do not question ourselves that we may be wrong then we are in danger of our own minds misleading us.
But with God, He is never wrong, so we can get the truth from Him.
