The Lord created the heavens and the earth in six days and then He rested. He rested from His work. The Lord has given all of us work to do.
Genesis 2:1,2 Thus the heavens and the earth were completed, and all their hosts. By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done.
Jesus worked when He was on earth.
John 4:34 Jesus said to them, “My food is to do the will of Him who sent Me and to accomplish His work.
Jesus glorified the Father by accomplishing the work which He had given Him to do.
John 17:4 I glorified You on the earth, having accomplished the work which You have given Me to do.
The Lord wants us to work for eternal food and not just for food for our physical bodies.
John 6:27 Do not work for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give to you, for on Him the Father, God, has set His seal.”
The Lord says that if we do not work then we have no right to eat. The Lord has given all of us work to do. Some work we get paid for and other work we do not receive financial compensation. We need to be doing the work He has given us to do.
II Thessalonians 3:10 For even when we were with you, we used to give you this order: if anyone is not willing to work, then he is not to eat, either.
Those who do not work need to be exhorted to work. Work is part of a disciplined life and the word disciple comes from the word discipline. The Lord wants us to lead disciplined lives.
II Thessalonians 3:11,12 For we hear that some among you are leading an undisciplined life, doing no work at all, but acting like busybodies.Now such persons we command and exhort in the Lord Jesus Christ to work in quiet fashion and eat their own bread.
Joy and contentment are related. Happiness comes from doing the work that the Lord has given you to do and being the person that God has created you to be.
