Numbers 13:29 The Amalekites dwell in the land of the south: and the Hittites, and the Jebusites, and the Amorites, dwell in the mountains: and the Canaanites dwell by the sea, and by the coast of Jordan. 31 But the men that went up with him said, We be not able to go up against the people; for they are stronger than we.
Numbers 13:32 And they brought up an evil report of the land which they had searched unto the children of Israel, saying, The land, through which we have gone to search it, is a land that eats up the inhabitants thereof; and all the people that we saw in it are men of a great stature. 33 And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight.
They considered the size of the giants, in contrast to their own selves, and, in their minds, it was a no-brainer that they could not win. Be very careful of experts who do not include the God-factor in their reckonings, for they mostly deal in finite limitations, and the counsel they give could cause you to squander your golden opportunities, in some cases. That was the problem with king Saul, who seemed to have difficulty seeing beyond the finite, to behold the infinite.
When faced with danger or difficulty, he would instantly refer to the realm of mortals alone, using only finite calculations to guide his decisions. For instance, when David offered to smoke out the giant Goliath, Saul, who was an expert in war, didn’t think it possible, and based upon strictly humanistic modes of thought, he made unequivocal statements pertaining to the mission impossible.
1st Samuel 17: 32 And David said to Saul let no man's heart fail because of him; thy servant will go and fight with this Philistine. 33 And Saul said to David, you are not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth.
May God add His blessing to the study of His word. “Good night” and God bless!
