How does God choose and still allow free will?
But the LORD said to Gideon, "There are still too many men. Take them down to the water, and I will sift them for you there. If I say, 'This one shall go with you,' he shall go; but if I say, 'This one shall not go with you,' he shall not go." So Gideon took the men down to the water. There the LORD told him, "Separate those who lap the water with their tongues like a dog from those who kneel down to drink." Three hundred men lapped with their hands to their mouths. All the rest got down on their knees to drink. Judges 7:4-6
J. Vernon McGee called this, “one of the finest lessons concerning divine election and man's free will.” McGee went further on to say, “This is the way they work together. God said to Gideon, "I am going to choose the men that I want to go with you, but the way I will do it is to let them make the choice. Bring them down to the water, and the ones who lap water like a dog, just going through and throwing it into their mouths, are the ones I have chosen. You can put aside those men who get down on all fours and take their time drinking. I don't want them." 3
