God Creates Perfectly
For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for it is made holy by the word of God and prayer. 1 Timothy 4.4-5
God created the whole world. When He created it, He did not create good things and bad things. He did not create things to be used and things to be avoided. He did not create anything useless. He created perfectly. Everything that He made served its purpose and served it well.
Things are not perfect anymore. Sin corrupted everything when it entered the world. But this does not mean that there is no good left. The good in the world stems from the good that God instilled in the beginning. Our God is good, and the good in the world still reflects His glory. Things did not go from being completely good to completely evil. Instead, all things have been skewed; tainted with sin. This means that all things bear fingerprints of the Creator as well as the impact of sin.
Your job as a Christian is to seek out the good that is in the world; to receive with joy, those things that God created for your joy. You are to approach the world as a miner panning for gold, sifting through the debris to find the glimpses of God that shine through and point you to His greatness.
