God makes everything happen at the right time. Yet none of us can ever fully understand all he has done, and he puts questions in our minds about the past and the future.
I saw everything God does, and I realized that no one can really understand what happens. We may be very wise, but no matter how much we try or how much we claim to know, we cannot understand it all.
My Father has given me everything, and he is the only one who knows the Son. The only one who truly knows the Father is the Son. But the Son wants to tell others about the Father, so that they can know him too.
The seeds that fell among the thornbushes are also people who hear the message. But they start worrying about the needs of this life and are fooled by the desire to get rich. So the message gets choked out, and they never produce anything.
