In our Bible reading for today, we come to Joshua 13-14 where God promises an elderly Joshua that he WILL complete what he started. This is a theme we see again in the New Testament:
And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ. Philippians 1:6
When Joshua had become old and more or less enfeebled, the Lord appeared unto His servant, and after informing him that there remained yet very much land to be possessed, and naming some of the places and peoples to be conquered, He declared, “them will I drive out from before the children of Israel: only divide thou it by lot unto the Israelites for an inheritance, as I have commanded thee” (Josh. 13:6). It had been so with Moses: under God he had begun the task of occupying Canaan (namely that part thereof which lay to the east of Jordan), but only a small beginning had been made. Joshua had been used to carry forward the enterprise considerably, yet it was far from being completed—others would be raised up later to effect the Divine purpose. And it has been the same ever since. A start was all that was made by the apostles in the evangelizing of the Gentiles, for when the last of them expired there remained yet very much land to be possessed. Calvin and Luther were mightily employed in delivering God’s people from the deadly shackles of Rome, yet when the last of the Reformers was called home how much yet remained to be accomplished!
