The meaning of design is the process of envisioning and planning the creation of an odject. It is also a pattern, system or rhythm.
The Most High took time to design not only you but the life you would lead. The experiences you would have to produce an outcome or expected end.
DNA holds all the information of not only yourself but 6-8 generations of your ancestors. That would mean that when designing you, your life was linked to those that came before and those after. But he didn't stop there.
The Most High new the people you would encounter, who you would marry or divorce. The children you would have... Even your best friend, he knew that as well.
Your experience in life is not a mistake but is a part of a Master Plan. No matter what happens good, bad or indifferent he knew it. Because he set in motion a series of events to create you. Without you the Masterplan doesn't work.
“I will give thanks and praise to You, for I am fearfully and wonderfully made; Wonderful are Your works, And my soul knows it very well. My frame was not hidden from You, When I was being formed in secret, And intricately and skillfully formed [as if embroidered with many colors] in the depths of the earth. Your eyes have seen my unformed substance; And in Your book were all written The days that were appointed for me, When as yet there was not one of them [even taking shape]. How precious also are Your thoughts to me, O God! How vast is the sum of them!”
