When an artist decides to make a painting, he "conceives" a picture. He then takes out the canvas, brushes and paint. After getting out all he may need, the artist starts picking out the colours and brushes he wants to use...then; he begins! Now, somewhere during the process of this painting he comes to the point where he decides to use a very fine brush to put in the some detail on the painting, but for some reason that brush just does not want to work...and having to finish the painting, the artist chooses another brush which even though it is not as fine (able) as the previous brush becomes a skilful wand in the hands of the artist, not due to the capabilities of the brush...no, due to the willingness!
Mat 22:14 for many are called, but few are chosen...
I believe this scripture does not refer to God having favourites and therefore does not want to choose some, but rather because some are consistently refusing God's grace and love to shape and mold their hearts.
Do you realize just how much God loves you...? He created the universe with words, yet He took the time to mold, shape and create you...this has to make you wonder; who is this God that thought of me before the foundation of the earth and if He thought of me, that must mean that I am worth so much in His hands...?
