"That is why I was angry with that generation, and I said, 'Their hearts are always going astray, and they have not known my ways.' So I declared on oath in my anger, 'They shall never enter my rest'" (Heb 3:10-11).
Technology is supposed to make our ability to accomplish things easier and make us more productive. I love the technology gadgets available to us today. In twenty years these will seem as old and archaic as the eight track player. (See, some of you don't know what that is.)
Research reveals that the average person is working much longer hours today because we literally can work from anywhere. Our technology allows us to stay in constant contact with others, which means we are always on call. Unless we intentionally set boundaries, we will never rest from our work.
God got angry with the people of Israel because they did not know His ways. They failed to recognize the boundaries He had set for them that would ensure a spiritual and physically successful life. They chose to disregard His ways. This disobedience led to their inability to enter God's rest.
God's rest means that we can actually do our work and still be refreshed through His Spirit in our inner man. It is the opposite of sweat and toil. It means that the fruit of our work comes as a result of abiding in the vine of His grace and power. Jesus said you can do nothing (worthwhile) unless you are connected to the vine.
In order to do this you and I must do two things. We must understand His ways and we must do His ways. When we follow these two things, we will begin to experience His supernatural rest in all of our endeavors.
