We mature like seed awaiting a harvest.

James 5:7,8

“Therefore be patient, brethren, until the coming of the Lord. See how the farmer waits for the precious fruit of the earth, waiting patiently for it until it receives the early and latter rain. You also be patient. Establish your hearts, for the coming of the Lord is at hand. Do not grumble against one another, brethren, lest you be condemned. Behold, the Judge is standing at the door!”
