Proverbs 22:29

See you a man diligent in his business? he shall stand before kings; he shall not stand before mean men

An ability that has not been good enough to have been known about you by other people cannot elevate you to greatness. King David was very instrumental in fulfiling God’s purposes in Israel but God did not use him until he was properly prepared. Several great stint seen in David as raw talents at the time of his anointing and victory against Goliath had become improved skills and abilities at his crowning as King of Israel. Evidence of preparedness is seen in every of David’s successful efforts. If a talent must bring you before kings and princes, it will not be without preparation. God would not have brought Joseph before the king (Pharaoh) unprepared. A crude talent in you cannot place you before kings or princes. For this reason brethren, be good and improve on every good things. At least one of these will take you to greater places.

When you have worked on yourself towards perfecting the use of your talent there will not be any reason to be ashamed of using it at any available opportunity. This is necessary! I wonder, “if Joseph has not made use of the opportunity when it was available, how could he have been known as dream interpreter?”. He identified opportunity to solve challenges with his talent before he could bring it to light. A talent known only to the ceilings of your home will not take you places unless it is brought under the light of the sun.

Acknowledge God as the owner of the talents and not you.

Genesis 40:8 … And Joseph said unto them, do not interpretations belong to God?… 

Genesis 41:15-16

15  And Pharaoh said unto Joseph, I have dreamed a dream, and there is none that can interpret it: and I have heard say of you, that you can understand a dream to interpret it.

 16  And Joseph answered Pharaoh, saying, It is not in me: God shall give Pharaoh an answer of peace

You are only the vessel (carrier) for the  talent but God owns both the vessel (which is you)  and the content (which is the talent).
