John 9:4 I must work the works of Him who sent Me while it is day; the night is coming when no one can work.
Jesus knew He had to complete all the work assigned to Him through the scriptures; and He had no problem with doing it all.
I know we all get tired and weary, we all find it hard to do things we do not like doing; but give a thought to what Christ had to go through.
As long as there is work to be done for Christ, we should be more than willing to get on and do it without the complaints we throw out for just about everything else.
Just do it!
