While all truth is God’s truth, there are also ideas that are not true at all. As we study, we need to discern between good knowledge and evil. You need a filter on everything you study and hear.
If your journey is bigger than your map shows, you need a bigger map or you will not complete the journey without getting lost. What guides your search for the Kingdom of God? All roads do not lead to the same place.
John Piper said,
Alongside “All truth is God’s truth,” we need to say, “All truth exists to display more of God and awaken more love for God.” This means that knowing truth and knowing it as God’s truth is not a virtue until it awakens desire and delight in us for the God of truth. And that desire and delight are not complete until they give rise to words or actions that display the worth of God. That is, we exist to glorify God, and merely knowing a truth to be God’s truth does not glorify him any more than the devil does.
Jesus certainly found this to be true of Israel. There were those who heard him and responded in faith. Others could not accept anything he said. They heard his teaching but did not fully receive it. They continually found ways to discredit and doubt.
Belief requires taking teaching to heart. The doubters of Jesus held on to incomplete truths and never came to the knowledge that would make them free men and women. If you truly believe the Teacher, you are really a student.
The Jews who heard Jesus teach belonged to a place called Israel. Jesus was giving them truth that would move them to a new place called ‘The Kingdom of God’, where all were welcome. Their frame of reference was not big enough to include a larger perspective of God’s Truth.
Leonard Hjalmarson said,
Humans develop mental maps as aids in orienting in a complex world. It isn’t only our attention “span” which is limited; it’s also our attention bandwidth. Mental maps are like lenses with which we see the world, and they vary in breadth and detail. With time and engagement and work, our lenses gradually expand and the scope
A larger map allows you to go further, but also to return home. And so, we study to find God in all places. The gospel is at work in us to increase our attention bandwidth.
