Only be strong and very courageous, to observe to do according to all the law, which Moses my servant commanded you: don't turn from it to the right hand or to the left, that you may have good success wherever you go.
Joshua was especially exhorted to continue in the path of obedience. He was the captain, but there was a great Commander-in-chief who save him his marching orders. Joshua was not left to his own fallible judgment, or fickle fancy, but he was to do according to all that was written in the book of the law. So is it with us who are believers. We are not under the law, but under grace; yet still there is a gospel rule which we are bound to follow, and the law in the hand of Christ is a delightful rule of life to the believer. We are not to follow, in the service of God, our own fancies. We are not allowed to frame regulations according to our own conceptions, but our direction is, “whatsoever He saith unto you, do it.” His servants shall serve him, his sheep follow his footsteps, his disciples obey their Lord, his soldiers fulfill his pleasure: “By their fruits ye shall know them.” If we are not obedient unto Christ, we may rest assured that we have not the spirit of Christ, and are none of his.
