I Samuel 17:34-36 ESV
But David said to Saul, "Your servant used to keep sheep for his father. And when there came a lion, or a bear, and took a lamb from the flock, I went after him and struck him and delivered it out of his mouth. And if he arose against me, I caught him by his beard and struck him and killed him. Your servant has struck down both lions and bears, and this uncircumcised Philistine shall be like one of them, for he has defied the armies of the living GOD.
I want to remind you today, that whatever you're facing, remember that this is not your first rodeo. Check your references, I am sure you will find that GOD has brought you through some other things in your past. Many of which are far worst than what you are facing now.
Like David, when Saul told him that he could not fight Goliath because he was too young. David wasted no time giving Saul his references. Today, don't waste anytime giving the enemy yours. When it's said you can't do it; or you won't make it out this time. Kindly remind the enemy, that you've faced far worst and that this giant he has concocted will be no different. This situation will see its end in JESUS name, just like all the rest.
Stay encouraged and hold on. Victory is here!
