Samson prayed. “Sovereign Lord, remember me again. O God, please strengthen me just one more time. WIth one blow let me pay back the Philistines . . . ”
Then he did what he could do. Samson put his hands on the two center pillars that held up the temple and pushing against them, he prayed, “Let me die with the Philistines (from Judges 16:28-30).”
Pray, then do what you can do. God will do what He can do (which is anything He wants!!)
