He does speak to the world, through the pages in the Bible. 2 Timothy 3:16,17 assures us: "All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, so that the man of God may be fully competent, completely equipped for every good work."
We can meditate on God's dealings with his people in the past to understand how he feels today! For example, at Isaiah 48:17,18 we can sense God's earnest desire for our benefit. It says,
"This is what Jehovah says, your Repurchaser, the Holy One of Israel:
“I, Jehovah, am your God,
The One teaching you to benefit yourself,
The One guiding you in the way you should walk.
If only you would pay attention to my commandments!
Then your peace would become just like a river
And your righteousness like the waves of the sea."
