1 Samuel 17:33 And Saul said to David, Thou art 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.
David is again being judged on outward appearances. It is not the size of the man in fight but the size of the fight in the man. What Saul doesn’t know is that David has learned to trust God. David knows that God has used him in the past and will use him again. Saul sees youth but David sees God using him even though he is but a youth. Would to God that we would begin to look on the character, desire, and heart of a man to know how God will use him.
David may have been young but God had been preparing him for a long time. He may be but a youth but God has been preparing him for just such a time as this.
Notice also that Saul believes that he can’t be used because he is a youth but Goliath had also been a man of war since his youth. Could it be that we spread doubt and fear instead of faith and power? Are we guilty of scaring the youth instead of motivating them? Do you shrink people or stretch them? I would have no desire to cause fear when God could use me to encourage.
