“Judah could not dislodge the Jebusites, who were living in Jerusalem; to this day the Jebusites live there with the people of Judah.” (15:63)
If God wants something done, asks you to do it, and you can’t, do not despair. He will get it done with someone else. Look at 2 Samuel 5:6-7.
“The king and his men marched to Jerusalem to attack the Jebusites, who lived there. The Jebusites said to David, “You will not get in here; even the blind and the lame can ward you off.” They thought, “David cannot get in here.” Nevertheless, David captured the fortress of Zion—which is the City of David.”
The Jebusites lived in Jerusalem over 200 years before they were displaced by David. Of course they thought they were safe. But God accomplishes His purposes one way or another.
Just as Mordecai said to Esther, “If you remain silent, deliverance for the Jews will arise from another place.” He was sure God would save them somehow, but then he added, “but who knows that you have come to this royal position for such a time as this?”
Indeed, David finished a lot of the work left by Joshua. He expanded Israel’s boarders and Solomon expanded them even further. Esther rose to the challenge and was used to bring salvation to the Jews in the whole Persian Empire. Ultimately everyone’s successes and failures were fulfilled in Christ. He came to do, and perfect, the work begun, and left undone, by His people.
The Great Commission is our current, over-arcing directive, with a lot of little details along the way. His name will be exalted among the nations. Will you be involved? Has He brought you to your current position and sphere of influence to reach people only you can reach? The Great Commission shouldn’t feel burdensome. It’s a Great Privilege to be involved in His work. Something that wasn’t possible for someone else, might be possible for you through the power of Christ.
Keep listening. Enjoy the obeying.
