John Piper, in a sermon, “Risk and the Cause of God,”
Our text is 2 Samuel 10, especially verse 12. “Be of good courage, and let us be courageous for our people, and for the cities of our God, and may the Lord do what seems good to him.”
The Amalekites had shamed the messengers of Israel and made themselves odious in the sight of David. To protect themselves they had hired the Syrians to fight with them against the Israelites. Joab, the commander of David’s forces, found himself surrounded with Amalekites on one side and Syrians on the other. So he divided his troops, put his brother Abishai in charge of one group, and took the other himself.
In verse 11, which we have looked at before, they pledged themselves to help each other. Then came this great word in verse 12:
Be of good courage, and let us play the man for our people, and for the cities of our God; and may the Lord do what seems good to him.
MAY THE LORD DO WHAT SEEMS GOOD TO HIM.
What does that mean? It means that Joab had made a strategic decision for the cities of God and he did not know how it would turn out. He had no special revelation from God on this issue. He had to make a decision on the basis of sanctified wisdom. He had to risk or run. He did not know how it would turn out. So he made his decision and he handed the results over to God. And this was right.
It is right to risk for the cause of God.

We don’t always know what the outcome would be when we step out in faith for our Lord. However, we have no reason to believe that the results would bring glory to the Lord. Therefore, let us not be anxious about what will happen when we serve the Lord. God will never let Himself look foolish.
