There are many biblical passages that can help your family see, understand and marvel at God's wonderful creation. One particular passage helps me in my own quest to praise my God more often for all that He is - for all that He created.
Psalm 19 (The New Century Version) is my favorite for reminding me of the obvious; the amazing; and the divinity of design:
"The heavens declare the glory of God, and the skies announce what His hands have made.
Day after day they tell the story; night after night they tell it again.
They have no speech or words; they have no voice to be heard.
But their message goes out to all through all the world; their words go everywhere on Earth."
Why not take the time to memorize the above passage, and then encourage your children to do the same? On this very night - in the warmth of the summer eve - take a stroll outside and marvel at the countless stars in the sky, and how they silently and boldly declare the God that created them - that created us. Talk about God's intentional and marvelous design, and of his loving invitation for them to join him in becoming designers too.
God calls all of us to join him in the act of creating - to harness and develop the many talents, tools and materials that HE created from nothing and use them ourselves to create new beautiful things. Perhaps your child loves to paint, or has a knack for sculpting, or designing clothing. Maybe your son or daughter loves the written word, or speech; maybe they have a knack for envisioning processes, techniques, or systems. Does a budding musician live in your home? Whatever the talents or interests - encourage your children to explore and develop.
And above all else, take the time to help them to tap into the inspiration of the great Creator - to the One who made it all - to discover that to design, is Divine.
