A talent that is not polished is a waste of potential. Talent is a gift given to all of us by our maker, and he expects us to develop and groom it for the benefit of ourselves and to humanity in general. Unfortunately, there are so many people in the world that has failed in this regard, they have discovered their talents but yet they are redundant with the use of such talents.
The bible was very unequivocal about waste of talents. There was a certain wealthy man(master) that gave out different talents to three individuals. The first he gave five, the second he gave two and the last he gave one. What he expected of them was for them to multiply the talents given to them. The first person traded with his and doubled the talent received, and the second also did same and double his too but the last person failed to make use of his and he went and buried it, all in the name of it been too small. On the master return, he inquired from them how they have used the talents given them. They all narrated how they have fared with their talents. The first and second got commended for judicious use of theirs. When it got to the last, he claimed the talent he received was too small thus he went and buried it so that if the master come asking for it he would give it back him in the same measure he received it. For his action, his master despised him and took back his talent and drove me out of his presence calling him a waster of talent
The moral lesson is, we can all develop the unique talents given to us regardless of the amount of it we were given individually. The onus falls on us to do the needful in ensuring our talents don't turn out waste.
