You water plants and they grow. You plant the Word of God in your heart and it brings forth good fruit every time.
Read: Isaiah 55:10-11
10 “The rain and snow come down from the heavens
and stay on the ground to water the earth.
They cause the grain to grow,
producing seed for the farmer
and bread for the hungry.
11 It is the same with my word.
I send it out, and it always produces fruit.
It will accomplish all I want it to,
and it will prosper everywhere I send it.
