My pastor often says, "If you want to know God's will but aren't hearing from Him, go back and do the last thing you're sure He did tell you to do (but haven't yet done); once you have, then He'll reveal to you the next step."
It only makes sense. If God gives us understanding (light) on something, and we do not act on it - we are saying back to Him either “I don’t believe You.” or, “I am unwilling to apply that truth to my life.”
Like a child refusing to eat his supper, a parent will not then provide dessert. Or say, “Oh, then what would you like to eat? I’ll fix you whatever you want....” When God gives light/understanding, it is because He knows we need to see something we have not seen before, to know something we have not known before. He knows what we need. If we reject that, why would he give more?
Oswald Chambers astutely pointed out how new light wholly depends on our acting on what light He has already given us.
On the other hand, his infinite mercy and grace NEVER cease to pursue us - unless we harden our hearts against Him.
