"For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy."
The balance between work and rest is difficult to manage at times. In the correct order though we need to rest after we do the work in front of us. Resting before we do the work is laziness, and once we become lazy it is very difficult to come out of. When God gives us direction and a job to do we need to make sure and complete that first and foremost. Once that is complete we can rest and rejuvenate our body to be ready for the next task the Lord gives us. Always remember this is a marathon and not a sprint!
