In the bible, a god who never speaks or intervenes is called an idol. When training at university, I picked up from some ministers and some ministers in training, thankfully not all, that this was the god they believed in and prayed to and preached to others. In the same bible it is a cause of concern to the people of the true and Living God, a time for searching their hearts, when He stops speaking and intervening in observable and desirable ways. Such concern can be the beginning of revival: “Where is the God of Abraham, Isaac and Jacob? Where is the Lord, the God of Elijah? Where is the God and Father of our Lord Jesus Christ? Where is the God of the Apostles?” Well, He is where He has always been and can be found in the way He has always been found. He never changes and has never moved the goal posts.
So when heaven seems as brass it is good for God’s people to humble themselves and ask “why?”. It may be that they will find out all is well and simple trust is required. It may be they will find that all is not well and repentance is being awaited.
