Today, read 2 Samuel 20, Ezekiel 27.
This devotional is about 2 Samuel 20.
Joab was an outstanding military leader for David. Violence, however, was not just his thing on the battlefield; it was just about the only language he knew. Earlier in 2 Samuel, his brother Asahel was killed in battle by Saul’s top general Abner (2 Sam 2:22-32). Joab retaliated by murdering Abner in a non-military setting (3:27). That happened early on in David’s administration as king of all Israel and he did not deal justly with Joab, though he did condemn his actions (2 Sam 3:29).
David paid a price for not dealing with Joab. In chapter 18 Joab killed David’s son Absolom against David’s explicit command and when Absolom was completely defenseless (18:9-15). As a result, David turned over leadership of his army to Amasa in chapter 19. As we read yesterday in 2 Samuel 19:13, David said, “May God deal with me, be it ever so severely, if you are not the commander of my army for life in place of Joab.’”
Here in chapter 20 Amasa had an opportunity to serve David and demonstrate his prowess as a military leader. Sheba rebelled against David (vv. 1-3) and David commanded Amasa to get the men of Judah ready to fight against Sheba. Verse 5 told us, however, that Amasa failed to do what David commanded. “But when Amasa went to summon Judah, he took longer than the time the king had set for him.” To keep matters from getting worse, David had to turn to Abishai and Joab used the uncertainty of leadership to reassert himself as Israel’s military leader again (vv. 9-10, 13-23a).
The lessons here are two:
Procrastination is a costly error for leaders. When verse 5 says that Amasa “took longer than the time the king had set for him” I interpret that to be describing some amount of incompetence as a leader. David was an experienced fighter and leader; he knew how long it should take to muster the men of Judah and prepare them for battle. The fact that Amasa “took longer than the time the king had set for him” suggests either a lack of persuasion skills or (more likely) some amount of procrastination. Procrastination is a killer because it squanders opportunity. When you and I do other things to avoid the thing we should be doing, we are wasting time, energy, (possibly) money and opportunity. Except for money, all of those things are impossible to recover. If you’re going to be an effective leader, then, don’t be crippled by an inability to decide and take action.
Effective people under your leadership may get the job done but at what cost? Joab was very successful as a military leader but David treated him as untouchable because of his great success. That was a mistake; David excused the unjust way Joab acted and it came back to hurt David in multiple ways.
As you serve the Lord in your daily work, don’t procrastinate; get to work ASAP and be effective at whatever you are planning or leading.
Similarly, if you are a leader with an employee who is effective but cruel to others, fire that person ASAP. It will be hard to do because he or she is so effective but it will save you time, money, and stress in the long run.
