I Samuel 17:42 And when the Philistine looked about, and saw David, he disdained him: for he was but a youth, and ruddy, and of a fair countenance.
Think of it. David has now been disdained by his dad and family, by Samuel the prophet, by Saul the king and now by Goliath his enemy. Each have seen only what the human eye can see.
God is seeing a very different story. They see a red headed or red faced, good looking boy. (The word ruddy indicates the color red. Some think that it was talking about his skin color and other his hair color) God saw a warrior and a future king.
If you will disciple men you must see beyond the outward and to the man or woman that will be after God does a miracle work in their lives. If you are the youth that is reading this note then hang on to what God is doing in your life.
Do not be discouraged by the opinions of family, friends, leaders, and even spiritual leaders. God is the one that will do the work.
Do not be cocky but be certain that God has called you and that God will use you if you will but obey Him and honor His word. If you are the discipler or leader trainer then get involved in building confidence in your disciple.
Help him to prove his weapons by much practice. Help him to kill the lions and the bears so that he will be able to stand against the onslaught of doubt and fear that will be hurled at him. Pastor be an encourager and not a discourager.
