At the end of his life, Joshua presents the Israelite people with an ultimatum:
Serve the Lord and throw away all other gods
OR
Forsake the Lord to serve other gods
At this “spiritual high” in Israel’s history, after they have just seen God miraculously destroy their powerful enemies, of course they choose the Lord, exclaiming “Far be it from us to forsake the Lord to serve other gods!” (Josh. 24: 16)
But Joshua then tells the people, “You are not able to serve the Lord,” and warns them of the consequences of turning away from the Lord. In their fervor, the people insist that they will serve the Lord, and they erect a monument to remind them of their decision.
The book of Joshua happily concludes that “Israel served the Lord throughout the lifetime of Joshua and of the elders who outlived him and who had experienced everything the Lord had done for Israel” (Joshua 24:31).
However, the rest of Israel’s history shows that forgetting and forsaking the Lord is not at all far from them. And Joshua knows this, so he clearly presents the full gravity of choosing to serve the Lord, which is no easy task. Yet to serve the Lord is the deepest cry of our hearts; we were made for this purpose. In our pride, we think we can do it, we can do all He requires of us. But Joshua is right in saying “You are not able to serve the Lord.” We, like the people of Israel, are so quick to turn from the Lord to our lesser gods of success, wealth, and popularity.
So where does that leave us?
At the cross.
God knew all along that we, in our natural inclination toward sin, were unable to serve Him as he made us to. That is precisely why He sent His beloved Son, Jesus, to free us from sin, to free us to serve Him. I am not able to serve the Lord on my own, so I must rely on the power of the Holy Spirit.
As I enter into a crazy week of meeting people and sharing the Gospel with them, my prayer is that I would rely fully on His strength, not my own. I really don’t have any.
