Because your mind has been captured!
You have been told NOT to think! Your MIND – the way you use your mind to think has been drugged, deluded and controlled. This world, this society and its people tells you how to think and mainly not to think for yourself at all and instead they train you to follow along, to go with the crowd and you blindly follow along without questioning anything. The world is as it is today because it does not think!  I am appealing to you to think, to think afresh! 
         Think, Think again! I’m appealing to you to think seriously!
Who made all of this? How did we get here? Question everything and seek real answers! Test everything, accept only what holds true. Take a fresh look and engage your mind. Think for yourself! But what are you to think about? First you must think again about God! Can you explain our universe without God? Can you not see that our Creator has left his mark on the whole of creation? As you see life collapsing all around you the call of the gospel is to think again and to think in the light of the teaching of the Bible.
           The great message of the Gospel;
                                You are called upon to think!
Our natural thinking is prejudiced and influenced by this world, corrupted going all the way back to and beginning with Adam’s fall and that’s why it has gone all wrong. You have acted in ignorance but now it is time to think again about all these things starting with God and how you relate to him. We all need a fresh approach! Repentance means thinking in a new way! Change your mind, start thinking in this new way and God will show you the truth in all things. 
​Therefore, THINK AGAIN, and CONVERT, for the blotting out of your sins, so that times of refreshing may come from the face of the Lord,                                                                Acts 3:19
Now in those days John the Baptist came preaching in the deserted places of Judea, and saying, THINK AGAIN! For the kingdom of Heaven has drawn near.                               Matthew 3:1&2
Jesus came into Galilee proclaiming the gospel of the kingdom of God, and saying, the time has been fulfilled, and the kingdom of God draws near. THINK AGAIN and believe in the gospel.                                                                                                                                                 Mark 1:15
And Peter said to them, CHANGE YOUR MIND and be baptized, each of you on the name of Jesus Christ to remission of sins. And you will receive the gift of the Holy Spirit.           Acts 2:38
