Our definition of rest and God’s definition of rest are quite different. We are thinking about taking a load off, closing our eyes, and sleeping for a week. It’s true that we need to take time to rest our bodies, because, what use are we if we cannot function? God considers it rest when we are no longer consumed by the power sin holds over our heads. We are at rest when we realize that we are no longer bound by religion, but are bound by love. We find our perfect rest in Jesus. He wants us to stop striving to please man and begin to look to Him to fulfill His perfect law, and that is to love Him and to love others as we love ourselves. When we change our minds and fall in love with Him, everything else in our lives will fall into place. It is then that we enter into His rest, the promised land! Once you get your heart in line with your head and you truly believe, rest will come.
And to whom did he swear that they would not enter his rest, but to those who were disobedient? So we see that they were unable to enter because of unbelief. Hebrews 3:18-19
